Not necessarily.  A level-one DOM does not require that much, and we
could elect not to deliver certain information (like comments).  I am
not suggesting that we deliver the information required for the
XML-specific DTD nodes.

If we omit comments, then SAX-J would have to return only the
following information:

- elements
- attributes
- PIs
- texts

This should be sufficient for building a useful DOM.  Strictly by the
book, we specify whether each attribute was specified or defaulted,
and we should specify which text is ignorable whitespace.



All the best,


David
