Two comments in reply:

1) A pox on processing instructions! If we had to use a
non-element SGML syntax, there is a perfectly good SGML
mechanism -- external entities -- for handling just this
kind of thing:

<!ENTITY foobar SYSTEM "">


If/when the URL is updated, only the entity declaration
would need to be redefined. But this would require
HTML browsers to be able to parse still more SGML.
Not necesarily a goal of this working group.

2) A more viable solution might be to introduce an <INCLUDE> element.

<DL> ....
<DT> foobar
<DD> <INCLUDE ID=foobar NAME="foobar" HREF=""
REL="subdoc" REV="glossary"
TITLE="The definition of foobar is...">


P.S. Looking at the HTML 3.0 spec, I am surprised to see the REV
attribute missing from both <A> and <LINK>. Why is that?

I'm glad to see a list of values for REL, but I wonder why
each begins with a leading capital letter. Since case is
significant for these attribute values, according to the DTD,
I would suggest that lower-case values be used. In fact, I wonder
whether we need to discuss that as a design principle.

Hmmm! Come to think of it, I don't think that we (HTML WG)
have any articulated and documented design principles.
