I noticed that it is legal to have nested STRONG elements (or EM elements).
Personally, I do not see the logic in this.

I recommend that the STRONG element be listed in the exclusion content
of the STRONG element.  The similiar can be said for the EM element.


    <!ELEMENT STRONG - - (%phrase.content)+ -(STRONG)>
    <!ELEMENT EM     - - (%phrase.content)+ -(EM)>

Any compelling arguments to the contrary?
