Yeah, indeed.  Sounds like some clarification is needed here in terms of 
which parts are document conformance and which parts are UA conformance.

They don't need to know what it "is" as long as they know what to do 
with it.  The spec should clearly specify what to do with it, of course.

Nothing special would be the default, no?

There's lots of "outdated nonsense" which conforming documents are not 
allowed to include, but which UAs still have to handle and hence the 
spec needs to specify handling for.  That's all the spec needs to do 
with it, though.

I agree that it should be made clearer that a document that uses it is 
non-conforming (assuming that's the intent, of course).

Sorry, I can't read minds very well.  Especially when there is temporal 
separation involved.  You'll have to ask the implementors from 10 years 
ago or so.
