XOM API for Processing XML with Java

[Randall R Schulz <rschulz AT sonic.net>]

Hi,

I'm just getting started with my first real XML project. As part of 
learning the landscape, I created a W3C XML Schema for my domain 
(first-order logic formulas and knowledge bases holding them). It was a 
rather frustrating exercise and it does not seem amenable to quite 
capturing my ideal representation for this content, though it's 
entirely possible I overlooked options not apparent to a novice.

So I kept surveying the XML and XML+Java processing landscape and found 
XOM and, of course, Relax NG. It seems that they might be a good choice 
for me but as part of deciding the precise set of technologies I'll 
use, I need to know what's involved with mixing XOM with Relax NG.

Is it possible? If so, is it straightforward? I could not find anything 
specific or definitive addressing this issue.

Thanks in advance for any information, advice or pointers.
