GC Architecture Crosswalk with Archimate

## User Story
As a Canada-ca/architecture contributor
I want a cross walk between GC policy instruments and Archimate artifacts
So that I can effectively decompose GC Elements into Archimate elements

## Work to date:
This is an ongoing attempt to create such a crosswalk for my own architectures, however it has not been vetted or validated by the community.

Open the linked MappingTogafArchimate2GovernmentOfCanada document first and compare its mappings with the issue’s stated GC policy and ArchiMate goal. Done means producing a clearly scoped, community-vetted crosswalk, but the issue names no repository file, test, or concrete validation criteria.
