[oXygen-user] RelaxNG and Schematron

[Sorin Ristache]

Hello Christian,

You did not send layout_definitions.rng so I cannot test the whole 
schema on an XML document. Your schema has at least two problems:

1. You have to use the ISO Schematron namespace in a RELAX NG schema, 
not the Schematron 1.5 one, that is:

xmlns:sch="http://purl.oclc.org/dsdl/schematron"

2. You have to specify the target namespace of the schema in the XPath 
expressions:

   <sch:ns prefix="layout" uri="http://www.docscape.de/layoutV4.2"/>

   <sch:pattern>
     <sch:rule context="//layout:Regel[@datensatz and @name]">
         <sch:assert
           test="count(//layout:Regel[@name=current()/@name and
           @datensatz=current()/@datensatz]) le 1"


Regards,
Sorin
