If this attribute is omitted, the endpoint that provides
the interface will be determined at deployment time.
If the VNF produces the LCM coordination interface, this
attribute may be omitted or may have the value 'VNF', and
a VnfInterfaceDetails entry with the 'interfaceName'
attribute set to 'VNF_LCM_COORDINATION' shall be specified
in the related deployment flavour to signal where this
interface is exposed by the VNF.
If the VNF does not produce the LCM coordination interface
but coordination via this interface is needed, it is expected
that a management entity such as the EM exposes the coordination
interface, and consequently, this attribute shall have the
value 'MGMT'.";
