What are you parsing your generated XML with, and what is the error you are
getting? It could be happening for a couple of reasons. Whatever you are using
to do the parsing and validation of that XML may be assuming (incorrectly)
that if it sees a DOCTYPE, it has to do DTD-based validation. Whether or not
validation is being done, and what kind of validation, is up to the user of
the tool doing the parsing. (Note: Pointing to or directly providing schematic info is just
one of several
capabilities of a the document type declaration; it is also a source of entity
and default attribute declarations, and is normally checked for those
regardless of whether validation is being done.)
Another possibility is that the tool you are using does not recognize the
minimal DOCTYPE declaration that is being added to your document. Such a
declaration serves no real purpose, but is permitted to exist by the XML spec.
It is an often-overlooked 'feature' of XML though; some parsers may reject it
out of ignorance.
