Re: Remnant Xerces Dependency?

I don't mind having this dependency in place, but just to clarify, I already was
including xml-apis.jar.  I had to add xercesImpl.jar (which I downloaded
separately from the Xerces site) because it includes
org/w3c/dom/html/HTMLDOMImplementation, while xml-apis.jar does not.

Regards,

Aaron
