Re: New XML DOM and Java Tool

Hi Rod and All,

Sorry to take so long to respond.
The basis of the work is shown at:
Justin Couch is the main contributor on a lot
of the parser.
To me, the big deal is that we are using
Java/Java3D, but need the full W3C DOM,
with both static and dynamic aspects.
I still think XML and DOM are very basic to what
is required by OHS so I think this may be important
to whatever is being done. The 3D part of this work
will also be important when it is desired to provide
a user interface and mapping of content.

Thank You and Best Regards,
