DNG ReqIF Export shall export links between artifacts in different modules in <SPEC-RELATION-GROUPS>

Description

DNG ReqIF Export shall export links between artifacts that are in different modules in <SPEC-RELATION-GROUPS>.

Currently, DNG exports such links into <SPEC-RELATIONS>, not into <SPEC-RELATION-GROUPS>. The ReqIF Standard details how to export links in <SPEC-RELATION-GROUPS>.

Motivation / Reason

The current implementation of the DNG ReqIF Export of links between artifacts in different modules (export of links into <SPEC-RELATIONS>, not into <SPEC-RELATION-GROUPS>) is not compliant with the ReqIF Implementation Guide. The ReqIF Implementation Guide (Version 1.6) (Page 22, Chapter "Chapter 2.10 How to deal with RelationGroup elements") states:
"It is mandatory to put a SpecRelation in a RelationGroup at least when the SpecRelation is going across the boundary of one Specification AND both the source and the target SpecObject are part of a Specification."

Since the current implementation is not compliant with the ReqIF Implementation Guide, several ReqIF import tools cannot correctly import links exported by DNG ReqIF Export.

One of the technical reasons is that if a link is specified in a <SPEC-RELATIONS>, the ReqIF file does not specify the source module (module the source artifact of the link is in) and the target module (module the target artifact of the link is in). This makes is considerably harder or imposible for ReqIF Import tools to "find" the target artifact of the link, which is likely why the ReqIF Implementation Guide states that <SPEC-RELATION-GROUPS> must be used.
