New SGML declaration?

I may have this wrong, but as I understand it the SGML declaration for
HTML 4.0 has to be modified slightly to support hexadecimal numeric
character references.  Perhaps the W3C should issue an admendment or
something.  Or perhaps just add the neccesary corrections to the errata.
