Often you don't want the parser to validate. Remember all the times people
get bit by msxml's default validation, when they just want to add one entity
declaration with a DOCTYPE. This is one of thoses cases that beg for
validation and other DTD processing to be in separate processing steps. At
any rate, I think "most" people don't expect the processor to do anything
except add whatever DTD declarations they see in the document itself (the
internal subset), but they do expect them to be processed so that entities
can be defined, etc. That may not be completely logical, but "most" people
probably aren't up on what they think are the fine points.
