[oXygen-user] ISO Schematron validation?

[Syd Bauman]

SyncRO --

  What component does oXygen use to validate against ISO Schematron
schemas? Does oNVDL do that? Does jing? Have you used the XSLT
implementation of ISO Schematron? Have you written something of your
own? 

  I'm curious becase (as you may have read on TEI-L), I think TEI
should be using and recommending ISO Schematron as opposed to
Schematron 1.x, but it is *awfully* convenient to be able to use jing
for validation.
