Re: [xml-dev] Understanding the scope of XML catalog

["G. Ken Holman" <gkholman@CraneSoftwrights.com>]

Thank you!

Your thinking of alternatives also leads me to consider including an 
NVDL schema in the distribution. Then users can use that one schema 
to validate any XML document.

A quick search, though, doesn't help me find any examples of 
command-line NVDL processors that I could include as a JAR file in 
the UBL distribution. The 20151127 jing that I found appears to take 
in only an RELAX-NG argument as input.

Thanks, again!
