I'm not sure it is true.  If a DTD is specified in the xml the parser
*must* attempt to read it to ensure any defaulted values are present in
the XML, regardless of configuration.  Turning off validation (I think)
simply suppresses validation errors.  The only way I know of to parse an
xml file with a DTD specified (without access to the DTD itself) is to
implement a custom entity resolver.  Of course, you can edit the XML
file prior to transforming to remove the doctype, but regex'ing over xml
markup just feels wrong.  

I don't understand the benefits of using defaulted values, as anyone
studying the xml also needs to study the dtd to ensure they get the full
picture.  Seems crazy, really.
