I expect that it would be reasonable for this to remain a Note rather than anything more formal, but since I think the conclusions here should have some normative force on future recommendations, I wouldn't disagree if people think it should be promoted somehow.

As it is now explicitly cited, I would like to point out that in the StandardRegExt usage of ivorns is more than just a name, the fragment part is really expected to be a fragment of the resource returned by the main ivorn - it should point to a vstd:StandardKey type element within the XML Resource document retrievable from the ivorn - see
