            A notification about lifecycle changes triggered by a VNF LCM
            operation occurrence.

          schema:
            description: >
              This type represents a VNF lifecycle management operation
              occurrence notification, which informs the receiver of changes in
              the VNF lifecycle caused by a VNF LCM operation occurrence. The
              support of the notification is mandatory. This notification shall
              be triggered by the VNFM when there is a change in the state of a
              VNF LCM operation occurrence that changes the VNF lifecycle,
              including: * Instantiation of the VNF * Scaling of the VNF
              instance (including auto-scaling) * Healing of the VNF instance
              (including auto-healing) * Change of the state of the VNF instance
              (i.e. Operate VNF) * Change of the deployment flavour of the VNF
              instance * Change of the external connectivity of the VNF instance
              * Termination of the VNF instance * Modification of VNF instance
              information and/or VNF configurable
                properties through the "PATCH" method on the "Individual VNF instance"
                resource.
              Clause 5.6.2 defines the states and state transition of a VNF LCM
              operation occurrence, and also specifies details of the
              notifications to be emitted at each state transition. If this is
              the initial notification about the start of a VNF LCM operation
              occurrence, it is assumed that the notification is sent by the
              VNFM before any action (including sending the grant request) is
              taken as part of the LCM operation. Due to possible race
              conditions, the "start" notification, the grant request and the
              LCM operation acknowledgment (i.e. the "202 Accepted" response)
              can arrive in any order at the NFVO, and the NFVO shall be able to
              handle such a situation. If this is a notification about a final
              or intermediate result state of a VNF LCM operation occurrence,
              the notification shall be sent after all related actions of the
              LCM operation that led to this state have been executed. The new
              state shall be set in the "Individual VNF LCM operation
              occurrence" resource before the notification about the state
              change is sent. See clause 5.6.2.2 for further provisions
              regarding sending this notification, including in cases of
              handling LCM operation errors.

            the "detail" attribute more information about the source of the
            problem.

            If there is an application error related to the client's input that
            cannot be easily mapped to any other HTTP response code ("catch all
            error"), the API producer shall respond with this response code. The
            "ProblemDetails" structure shall be provided, and shall include in
            the "detail" attribute more information about the source of the
            problem.

            If the request contains a malformed access token, the API producer
            should respond with this response. The details of the error shall be
            returned in the WWW Authenticate HTTP header, as defined in IETF RFC
            6750 and IETF RFC 7235. The ProblemDetails structure may be
            provided.

            The use of this HTTP error response code described above is
            applicable to the use of the OAuth 2.0 for the authorization of API
            requests and notifications, as defined in clauses 4.5.3.3 and
            4.5.3.4.

            400 code can be returned in the following specified cases, the
            specific cause has to be proper specified in the "ProblemDetails"
            structure to be returned.

            If the request is malformed or syntactically incorrect (e.g. if the
            request URI contains incorrect query parameters or the payload body
            contains a syntactically incorrect data structure), the API producer
            shall respond with this response code. The "ProblemDetails"
            structure shall be provided, and should include in the "detail"
            attribute more information about the source of the problem.

            If the response to a GET request which queries a container resource
            would be so big that the performance of the API producer is
            adversely affected, and the API producer does not support paging for
            the affected resource, it shall respond with this response code. The
            "ProblemDetails" structure shall be provided, and should include in
            the "detail" attribute more information about the source of the
            problem.

            If there is an application error related to the client's input that
            cannot be easily mapped to any other HTTP response code ("catch all
            error"), the API producer shall respond with this response code. The
            "ProblemDetails" structure shall be provided, and shall include in
            the "detail" attribute more information about the source of the
            problem.

            If the request contains a malformed access token, the API producer
            should respond with this response. The details of the error shall be
            returned in the WWW Authenticate HTTP header, as defined in IETF RFC
            6750 and IETF RFC 7235. The ProblemDetails structure may be
            provided.

            The use of this HTTP error response code described above is
            applicable to the use of the OAuth 2.0 for the authorization of API
            requests and notifications, as defined in clauses 4.5.3.3 and
            4.5.3.4.

            400 code can be returned in the following specified cases, the
            specific cause has to be proper specified in the "ProblemDetails"
            structure to be returned.

            If the request is malformed or syntactically incorrect (e.g. if the
            request URI contains incorrect query parameters or the payload body
            contains a syntactically incorrect data structure), the API producer
            shall respond with this response code. The "ProblemDetails"
            structure shall be provided, and should include in the "detail"
            attribute more information about the source of the problem.

            If the response to a GET request which queries a container resource
            would be so big that the performance of the API producer is
            adversely affected, and the API producer does not support paging for
            the affected resource, it shall respond with this response code. The
            "ProblemDetails" structure shall be provided, and should include in
            the "detail" attribute more information about the source of the
            problem.

            If there is an application error related to the client's input that
            cannot be easily mapped to any other HTTP response code ("catch all
            error"), the API producer shall respond with this response code. The
            "ProblemDetails" structure shall be provided, and shall include in
            the "detail" attribute more information about the source of the
            problem.

            If the request contains a malformed access token, the API producer
            should respond with this response. The details of the error shall be
            returned in the WWW Authenticate HTTP header, as defined in IETF RFC
            6750 and IETF RFC 7235. The ProblemDetails structure may be
            provided.

            The use of this HTTP error response code described above is
            applicable to the use of the OAuth 2.0 for the authorization of API
            requests and notifications, as defined in clauses 4.5.3.3 and
            4.5.3.4.

            400 code can be returned in the following specified cases, the
            specific cause has to be proper specified in the "ProblemDetails"
            structure to be returned.

            If the request is malformed or syntactically incorrect (e.g. if the
            request URI contains incorrect query parameters or the payload body
            contains a syntactically incorrect data structure), the API producer
            shall respond with this response code. The "ProblemDetails"
            structure shall be provided, and should include in the "detail"
            attribute more information about the source of the problem.

            If the response to a GET request which queries a container resource
            would be so big that the performance of the API producer is
            adversely affected, and the API producer does not support paging for
            the affected resource, it shall respond with this response code. The
            "ProblemDetails" structure shall be provided, and should include in
            the "detail" attribute more information about the source of the
            problem.

            If there is an application error related to the client's input that
            cannot be easily mapped to any other HTTP response code ("catch all
            error"), the API producer shall respond with this response code. The
            "ProblemDetails" structure shall be provided, and shall include in
            the "detail" attribute more information about the source of the
            problem.

            If the request contains a malformed access token, the API producer
            should respond with this response. The details of the error shall be
            returned in the WWW Authenticate HTTP header, as defined in IETF RFC
            6750 and IETF RFC 7235. The ProblemDetails structure may be
            provided.

            The use of this HTTP error response code described above is
            applicable to the use of the OAuth 2.0 for the authorization of API
            requests and notifications, as defined in clauses 4.5.3.3 and

            400 code can be returned in the following specified cases, the
            specific cause has to be proper specified in the "ProblemDetails"
            structure to be returned.

            If the request is malformed or syntactically incorrect (e.g. if the
            request URI contains incorrect query parameters or the payload body
            contains a syntactically incorrect data structure), the API producer
            shall respond with this response code. The "ProblemDetails"
            structure shall be provided, and should include in the "detail"
            attribute more information about the source of the problem.

            If the response to a GET request which queries a container resource
            would be so big that the performance of the API producer is
            adversely affected, and the API producer does not support paging for
            the affected resource, it shall respond with this response code. The
            "ProblemDetails" structure shall be provided, and should include in
            the "detail" attribute more information about the source of the
            problem.

            If there is an application error related to the client's input that
            cannot be easily mapped to any other HTTP response code ("catch all
            error"), the API producer shall respond with this response code. The
            "ProblemDetails" structure shall be provided, and shall include in
            the "detail" attribute more information about the source of the
            problem.

            If the request contains a malformed access token, the API producer
            should respond with this response. The details of the error shall be
            returned in the WWW Authenticate HTTP header, as defined in IETF RFC
            6750 and IETF RFC 7235. The ProblemDetails structure may be
            provided.

            The use of this HTTP error response code described above is
            applicable to the use of the OAuth 2.0 for the authorization of API
            requests and notifications, as defined in clauses 4.5.3.3 and

            400 code can be returned in the following specified cases, the
            specific cause has to be proper specified in the "ProblemDetails"
            structure to be returned.

            If the request is malformed or syntactically incorrect (e.g. if the
            request URI contains incorrect query parameters or the payload body
            contains a syntactically incorrect data structure), the API producer
            shall respond with this response code. The "ProblemDetails"
            structure shall be provided, and should include in the "detail"
            attribute more information about the source of the problem.

            If the response to a GET request which queries a container resource
            would be so big that the performance of the API producer is
            adversely affected, and the API producer does not support paging for
            the affected resource, it shall respond with this response code. The
            "ProblemDetails" structure shall be provided, and should include in
            the "detail" attribute more information about the source of the
            problem.

            If there is an application error related to the client's input that
            cannot be easily mapped to any other HTTP response code ("catch all
            error"), the API producer shall respond with this response code. The
            "ProblemDetails" structure shall be provided, and shall include in
            the "detail" attribute more information about the source of the
            problem.

            If the request contains a malformed access token, the API producer
            should respond with this response. The details of the error shall be
            returned in the WWW Authenticate HTTP header, as defined in IETF RFC
            6750 and IETF RFC 7235. The ProblemDetails structure may be
            provided.

            The use of this HTTP error response code described above is
            applicable to the use of the OAuth 2.0 for the authorization of API
            requests and notifications, as defined in clauses 4.5.3.3 and
