Maybe.

OK, but we would have to use <!ELEMENT BODY O O (%body.content) +(INCLUDE)>
to ensure that the INCLUDE element can be placed at any point in an
HTML document body.

Do we really need REV and METHOD ?

I also left out URN, feeling that none of these attributes have seen
widespread useage over the last few years, so perhaps they are just
cluttering up the standard for little real benefit.

(They are still in the DTD - so I need to get the explanation 
 and DTD into sync again).

Comments please.

As they are SGML NAMES, aren't they case insensitve?

I have tried to do this and welcome suggestions for improvements.
