But surely not in the opposite direction, correct?  Which is presumably 
why trang is complaining.

FWIW, we had an analogous problem: we want to produce PDFs from XML 
documents about linguistics.  We chose DocBook as the base, and got rid 
of a ton of things in the RNG/RNC that were irrelevant to our use case, 
then added a few that we needed for linguistics.  The authors of our 
linguistics books use XMLmind (XXE), which I see someone else suggested. 
  But you prefer to stay with emacs, which is understandable.  I myself 
use a programmer's editor, but it doesn't do any schema validation (it 
does check for well-formed XML); so I post-validate against the schema.

BTW, we looked into the usual XML-to-PDF via XSL stylesheets, and 
decided they were not sufficient for our needs (right-to-left scripts 
embedded in left-to-right text, complex scripts,...).  Instead we use 
dblatex (not to be confused with the older db2latex), which as the name 
suggests produces a latex format, then use (xe)latex to produce the PDF. 
  This of course also needed modifications for our linguistic use case.
