1.  Unlike elements, where order is preserved, I do not believe that
an SGML parser must return attributes parsed as to order.

2.  SGML doesn't allow multiple occurrences of the same attribute in an
element.  I.e., you can't do <A HREF="1" HREF="2">.

3.  The HTTP/1.1 spec has facilities for specifying alternate representations,
but these only work if you can contact a server/proxy that knows such info.
A more robust design would include a mechanism for authors to specify 
alternative content locations in the document for content that might reside on 
different servers.

4.  Overloading ALT is problematic.  I had suggested that a convention of
space-separated URI's in an HREF (or SRC) like: <A HREF="1 2 3"> eenie meenie
minie </A> might work, but only for short URI's.  This doesn't break current 
implementations (they retrieve URI 1), but can look ugly in the URI box.
