  While processing well-formed XML document without DTD the validating SAXParser
invokes the method HandlerBase.warning() to report that the document has no DTD (see
test.java below). The XML 1.0 spec, 2nd edition, reads in section 2.8:

    "Definition: An XML document is valid if it has an associated document type
declaration and if the document complies with the constraints expressed in it."

  Since this document has no document type declaration, this statement is violated and
the document is invalid. Therefore the parser must invoked the ErrorHandler's error()
method rather than its warning() method.

  This bug is found in jdk1.4.0-b91 and affects the new JCK1.4 test:
