Re: finding the first unique tagName

XSLT can not see tags in the document (so doesn't have a concept of
tagName) but I'll assume you mean element name, even though elements and
tags are very differentt hings.

<when test="the current tagName/@idref is the first tagName/@idref in 
usage">


that would be in XSLT 2

test=". is (ancestor::usage[1]//tagName[@idref=current()/@idref])[1]"

or in XSLT 11 


test="generate-id() = generate-id((ancestor::usage[1]//tagName[@idref=current()/@idref])[1])"
