I provide a Relax-NG implemeantation as part of libxml2 python bindings.
When I started the RNG implementation I looked at a pure implementation
done in Python (found via google) but it implemented James Clark derivation
algorithm without merging the trees which led to exponential memory usage
and processing time, i.e. not usable except for very small examples.
Libxml2 doesn't handle the compact syntax directly, you can still
use trang to expand them to the XML version.
