There is currently a problem with the published regex for the ARCHETYPE_ID class in the openEHR support information model. It does not deal correctly with case, version ids, or special characters. In addition, the explanatroy text in section 4.2.2. does not correspond to the current reality of openEHR identifiers.
Update version id matching part to match a single part number only
Update change description to reflect recent discussions with ARB.
Reduce problem statement to essentials relating to the specifications rather than implementations of the spec.
