Thanks, John, that was my key point.

The doctype declaration files don't do that in any fashion
(e.g., via a %uri; sort of parameter entity or comment, at
least as far as I can tell).  It is possible some separate
Guide/docn mentions this, but I think it would be useful to
have a comment in the doctype declaration files next to the
entry for xml:base that says just what attribute values or
element content are in fact URI references to which xml:base
should apply.

More specifically, I wanted to be sure the TC agreed on just
what was the set of things to which xml:base applied.  I had
to miss the telcon so I don't know what was discussed, but it
appeared that there wasn't much discussion about this.
