I'd be cautious here.

Equating the XML communities and the xml2rfc communities is not correct.

There's an important distinction between the XML meta-language and the
xml2rfc language and its associated formatting tools.  Lots of places
express languages in XML DTDs and use one of the many XML parsers in
their tools to parse those DTDs.  That widespread adoption of the
meta-language and the resultant support for XML parsing libraries in a
large number of implementation languages and environments does simplify
the specification of the xml2rfc language and the generation and
maintenance of the xml2rfc program.  However, the actual community of
that uses the XML-based RFC authoring tools is a subset of the
contributors to the IETF; the maintainers of the xml2rfc formatter(s)
are a subset of that.  That smaller community is the one that is needed
to keep a working xml2rfc language and formatting program available to
the IETF.

It's by no means obvious to me that xml2rfc has reached a critical mass
of developers and users, nor that it will necessarily do so organically.
A financial IETF commitment to the system might mitigate that problem,
though I recognize the trolls under *that* bridge.  (Please do not take
this is not a slap at the rfc2xml developers.  I use the program and I
like the program.)

All that said, I do think that an XML-based encoding of RFC contents is
a good idea (seriously - that's not just lip service), but let's assess
the situation with open eyes.  If we're talking about changing formats
from ASCII -> rfc2xml, Bob's concerns about the long-term viability of
the xml2rfc formatting program(s) do need to be addressed, and the
assertion that there's a lot of interest and activity in XML doesn't do
so adequately.  IMHO.
