How can I say what you want to say without giving the appearance that the
URI-reference give information about a type governing the identified resource?

The problem is, I can appear to negate your sentence and come up with a
true statement:  "A URI-reference [...] can't point to any Web document
type."  It is an untyped reference.  There is no type until the pointer is
dereferenced.

That's why I went through all that long song and dance to construct the
subject of my sentence.  But this is a technicality.  Maybe I should be
more postive and direct:

-- revised draft suggested resolution --

1. There are a variety of formats that are appropriate for long
descriptions of images, and it is likely that new appropriate formats will
emerge.  

2. Referenced long description resources must be included in the scope to
which the Web Content Accessibility Guidelines are applied when the
referring document is in such a scope.  This is considered the appropriate
way to define the requirements on long description resources, rather than
by adding content type restrictions associated with the LONGDESC attribute
in format specifications.
