I'm in favor of this, particularly as it bypasses the waiting time
for HRRI to become a proper RFC.  But I don't quite see what language
to use to indicate that this paragraph (which does not have a
distinctive label, alas) should be in effect for XML, Namespaces 1.1,
XLink, etc. etc.

Can someone think up a proper invocation?

could understand this report.  Run out          cowan@ccil.org

can't make head or tail out of it.
