Description of problem:
The Docbook 5 instructions describe how to validate documents written against the RelaxNG schema with msv-relames.  However, the instructions don't work with the version of msv-relames currently available in Fedora.  Relames chokes on the embedded Schematron rules in the Docbook 5 schema, for example:

parsing    /usr/share/xml/docbook5/schema/rng/5.0/docbookxi.rng
element "s:ns" is not allowed here
  3:79@file:///usr/share/xml/docbook5/schema/rng/5.0/docbookxi.rng
  ...
element "s:pattern" is not allowed here
  1582:45@file:///usr/share/xml/docbook5/schema/rng/5.0/docbookxi.rng
  ...

I downloaded the latest available upstream release of relames, dated 20 March 2006, and it properly parses the Docbook 5 RelaxNG schema and applies the Schematron rules during validation.

Version-Release number of selected component (if applicable):
msv-relames-1.2-0.4.20050722.3.4.fc12.1.x86_64

How reproducible:
Always

Steps to Reproduce:
1. Write or acquire a document written against the Docbook 5 RelaxNG schema
2. java -Xss1M -cp `build-classpath msv-relames msv-msv msv-xsdlib relaxngDatatype isorelax xalan-j2` com.sun.msv.schematron.Driver /usr/share/xml/docbook5/schema/rng/5.0/docbook.rng <document.xml>
  
Actual results:
Lots of error messages from relames indicating that it does not understand the embedded Schematron rules.

Expected results:
Successful parsing of the Schematron rules and their application to the document being validated.
