oNVDL validation docbook 5

[Tim Arnold]

Hi,
I'm using the oNVDL java validator for my DocBook 5.0 documents. Otherwise, 
my doc system is python. I wonder if there is any work going on (or perhaps 
something I'm missing) to use python to validate DocBook 5 (using the rng 
files bundled with the DocBook5 distribution)

I think the catch with DocBook 5 rng is that it has embedded Schematron 
rules, which makes lxml not able to validate. I'm out of my depth here, but 
that's what I've heard.

Anyway, I'd sure like to streamline this using python rather than a 
subprocess call out to that java validator. Any suggestions or pointers 
welcome.

thanks,
