If it's a consolation I was called a "bellwether" [= "a rough raucous
fellow"] on the XML-SIG group. Passion is a valuable attribute.

XML-DEV has a strong tradition of exploring solutions in parallel with
official W3C efforts. 	
- SAX took place alongside the DOM and forms a worthy complement. 
- XSchema was a project to create DTD functionality in XML syntax. It has
certainly informed the current XML Schema working group

- SML is a project originating on XML-DEV to explore a "simple subset of XML".

various other discussions have informed the W3C activities in considerable
measure including namespaces, HTML, etc. I would expect that some of the
XSL WG were aware of the current discussions.

Personally I would value an activity that helped CSS and XML (including
FOs) interoperate more than they do at present. I find it frustrating to:
	- read an HTML DOM and not be able to extract the CSS information with
standard XML tools. There is no easy way to transform HTML+CSS into (say)
XSL-FO.
	- read an SVG file and not be able to parse the style attribute values
into XML [Parsing of path is another concern - but not directly related to
FOs].

If there isn't already, there needs to be a detailed account of
equivalences and transformations within the vocabularies and there also
needs to be an API for CSS (cf either DOM or SAX).

If you look back in the (pre-OASIS) archives you will see how these various
problems were tackled by members of the list and that will give hints as to
how to go ahead. It's probably a good idea to take the details offline and
report back as appropriate. I would expect you would get support and that
the exercise - whatever its findings - would be useful to current members
and to W3C spec designers.
