My copy works allright, so it is probably an issue with newer versions. Which
xalan version are you using?

This is a kludge I did some time ago , and I barely understood xerces code
then. Also, I had no access to docs, only to a copy of the sources. I did my
best to understand, but xerces is really difficult to follow.
I was concerned by the fact that Jetspeed was loosing a lot of time going to
the network to retrieve the netscape DTD, and it apparently ignored every
attempt to avoid it validanting some channels. This resulted in hundreds of
network attacks agains netscape (a DOS "feature :-)
I am testing your patch,. It looks all right, so I'm commiting it and taking
the JetspeedXMLReaderFactory class out of cvs.
Thanks for your help.
