 If one were expect a processor to implement this mechanism, then one could just as well expect a processor to implement the mechanism which is already implied by the namespace spec. Namely, to observe attribute default bindings for namespace attributes when reading the dtd. If specified in the internal subset for the root element of a dtd fragment which is described externally, the encoding is not significantly more complex then the implicit qualification proposed here. It also requires just implementing things which are already described... "Paul W.
