I've just recovered one from someone's trash:

ODD:
<http://hcmc.uvic.ca/people/martin/test/PL.xml>

RNG:
<http://hcmc.uvic.ca/people/martin/test/PL.rng>

The error on this one is "E [Jing] multiple definitions of 
"att.global.facs.attribute.facs" without "combine" attribute", but I saw 
something similar with att.ascribed on other machines if I remember 
correctly. Looking at this one, I realize he started from TEI Lite. I 
wonder if that's what the others did too?

I'm looking forward to seeing that. I hadn't taught the use of Roma in 
the last few years, and after yesterday I have a few ideas for minor 
improvements (for instance, the sanity check messages are 
programmer-messages and ordinary users couldn't make head or tail of 
them). But if I have time I'd also like to write a tutorial for using 
Roma, or at least some better presentation materials for myself.

Sorry I haven't been able to help with this. The last couple of months 
have been insanely busy. I do want to get involved as soon as I can, though.

Cheers,
Martin
