Subject: Characters in attribute values

I've had a look at the SGML declaration in the HTML 4 draft
and noticed the following:

----------quote----------
         NAMING   LCNMSTRT ""
                  UCNMSTRT ""
                  LCNMCHAR ".-"    -- ?include "~/_" for URLs? --
                  UCNMCHAR ".-"
----------/quote----------

So, how about that idea? Maybe ":" should be included as well
then, though, for dealing with absolute URLs. (Perhaps "."
and "/" could even be allowed as start characters too?) Would
such constructions cause any problems, for certain older
browsers or in some other regard?
