Hi Doug,

I don't know what the standardized way to serialize a org.w3c.dom.Document
is. There probably is a way, but I'm not sure what it is. I briefly looked
through the JAXP spec to see if I could find a clue, but I didn't see
anything. I did notice, however, that they explicitly say that
DocumentBuilder is not expected to be thread-safe, so holding on to one
instance may not be the best idea.

Thanks,
-Matt

Thanks for asking - I forgot to post a message about the entire JAXP
changes.  Can someone who actually understands all of this makes sure
I did it correctly?  And in particular what is the proper class I should
have
used there?

Hi Doug,

Doesn't the use of org.apache.xml.serialize.XMLSerializer force Xerces to
be present? Even if a user exploits your usage of JAXP to use a different
parser library (for parsing), they will now be forced to have Xerces
present also. Is XMLSerializer a standardized thing that I'm unfamiliar
with?

Thanks,
-Matt
