Your premise is false. DTDs are able to play with namespaces. The 
syntax isn't elegant but it does work. Either the DTDs must declare 
the prefixed names or the prefixes must be parameterized. XHTML, 
MathML, and many other XML applications use these techniques.

DTDs are not fundamentally incompatible with namespaces. The way I 
opften express it when motivating schemas is that DTDs are only 
"marginally compatible" with namespaces. However, for purposes of the 
current discussion tghhe difference between marginally compatible and 
incompatible is huge.
