editors supporting RNG and/or RNC?

I just found that Oxygen and XML Buddy support RNG and RNC. What else is out
there? 

All I need is emacs+nxml, but when people around me talk about tool support
for RELAX, I'd like to have the best possible list ready for them. Because
the Tools section of
http://www.oasis-open.org/committees/tc_home.php?wg_abbrev=relax-ng doesn't
mention Oxygen, I was wondering if anyone knows of anything else out there
that might be missing from the list. 

Let's not count an editor with the ability to pipe a buffer to a batch
validator and then show the error messages. I want to see editors that keep
a schema in memory and help you create documents that conform to that
schema. 

thanks,

Bob
