I would like to avoid making any assumptions about what sort of parser
is underneath.  Ælfred, for example, does not validate, but it does
read the content models and does distinguish ignorable whitespace.  In
fact, unless I'm mistaken, the four major Java-based XML parsers --
NXP, Lark, MSXML, and Ælfred -- _all_ use a DTD if present, and are
all capable of distinguishing ignorable whitespace.

With that in mind, would it be conformant behaviour for SAX to report
ignorable whitespace as regular character data when the parser
underneath is using the DTD (and, say, supplying defaulted attribute

All the best,
