Tim has stated the real issue quite plainly here.

I'll go a bit further on this topic though and suggest that XML doesn't need any 
markup declarations - in an intitial version. We have stated that a desirable 
goal for XML is that browsers be able to properly display documents without the 
need for markup declarations. We can assure achieving that goal by eliminating 
markup declarations from XML 1.0.

If we allow markup declarations, there will be a great temptation to use them 
and we will not achieve the goal of DTD-less processing. Markup declarations 
should become a part of XML after initial accepatance in order to support 
validation, etc.
