Aren't we all trying to do all things very well ;-) OK, I'll cut the jibes.

That's a Maven setup problem; shouldn't be a problem to route a
program's standard error into the log.

I'm afraid I can't help you with Eclipse's XML Schema aware XML
editing. I'm surprised to hear that this should be possible, but I'm
not relying on Eclipse support in my work.

"xjc file"? Do you mean a JAXB binding file? Why ever should it NOT
use well formed XML??

Calling xjc is documented in the JAXB download bundle in
./docs/xjc.html. A quick usage is available from xjc -help.
The contents of the bindings file is documented in The "JAXB
Specification", which is the fundamental documentation for JAXB.

A few basics are covered in Section 5,Customizing, of my JAXB tutorial.
