XML 1.0 non-validating parsers are required to process the internal
subset of the DOCTYPE.  They're only allowed to ignore the external
subset and references to external resources.  In practice, this means
that NVPs have to understand ENTITY declarations and ATTLIST
declarations whether or not they care about external DTDs.

For TAM, I left that work up to the application.  If it cares about the
contents of the DOCTYPE, it can do the parsing and retrieval and merge
that information with TAM events as they arrive.  If it doesn't care, it
doesn't care.
