Actually, there is little in the HTML+TIME proposal that precludes
application to XML (see also the W3C comments on the submission).  We
specifically included support for more abstract control of XML "sprinkled"
elements.  Nevertheless, much of the web content is HTML based, and many
authors have a large investment in HTML at this point.  It is a good thing
to look forward, but we must also aknowledge the needs of authors today.

Thanks for your comments -

Patrick
