Summary0007097: Clarification: ispresent function for elements of a "record of" or "set of"
DescriptionCurrently it is not defined what happens in case of e.g. ispresent(v_RecordOf[i]): Table 14 (clause 16.1.2) refers to "optional field in a record or set value or template" only.
On the other hand according to C.3.1 ispresent shall not cause an error.

=> Either applicability of ispresent shall be enhanced to cope with "record of" and "set of" too or an error shall be defined for this case (compilation or runtime error).

Note: at least with one compiler currently there are side effects resulting in runtime errors which are not directly related to ispresent.
TagsNo tags attached.

 STF discussion 03-08-2015: ispresent is not allowed to record/set of elements, this shall cause a semantic error. Solution to clarify: refer to table 14 in clause C.3.1. To table 14 add other language elements that can match omit (e.g. complete templates).

 Proposed resolution is in the draft uploaded to CR 7085 (http://forge.etsi.org/mantis/view.php?id=7085 [^]), es_20187301v040702.docx, please cross-check.

At the end of this working session the draft containing closed CRs will be uploaded to MTS drafts area. Further candidates to be included: CRs 6774 & 6934

 the proposed solution is wrong. ispresent should return true for all templates that are not AnyValueOrNone, Ifpresent or Omit, i.e. it should return false for all matching mechanisms that can match omit.

proposal: change entry in table 14 to:

"Determine ... is present or is assigned a matching mechanism that cannot match an ommitted field." (maybe with a note that those are omit, * and ifpresent)
