Re: [docbook-tc] Schematron problem in DB5 grammar

[Norman Walsh <ndw@nwalsh.com>]

/ Jirka Kosek <jirka@kosek.cz> was heard to say:
| today I found one problem in a way in which Schematron is embedded
| inside RELAX NG schema. Schematron specification requieres that rule
| elements are enclosed in pattern element. However pattern elements are
| missing in the schema. Some tools (in this case oXygen) are then
| unable to process embeded Schematron rules.

Alas, Kohsuke's MSV chokes on Schematron rules if they *are* wrapped
in pattern elements. I'll ask Kohsuke about it.

| I think that we could left RNC schema intact as it is mostly source
| format and I don't know any Schematron validator which is able to
| extract rules from RNC files. However I would suggest to surround rule
| elements by pattern element in RNG schemas. This should be matter of
| simple XSLT transformation in the build process. We also should add
|
| <s:ns prefix="db" uri="http://docbook.org/ns/docbook";
| xmlns:s="http://www.ascc.net/xml/schematron"/>
|
| to the top of RNG schema. This is good practice in Schematron because
| of YOU-KNOW-WHO (QNames in attribute values ;-) and some Schematron
| implementatios are not working without this.

Yes.
