RE: Predicate not allowed on root matching template ma

This syntax isn't allowed either in an XPath expression or in an XSLT match
pattern, either in 1.0 or 2.0.

No particular reason except that the grammar surrounding "/" is pretty
tortuous.

In XPath (but not in a match pattern) you can write (/)[predicate].

In XSLT 2.0 patterns you can write match="document-node()[predicate]"
