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 Christian Kosmowski wrote:

Hi there!

Due to some restrictions of XML Schema we are currently changing to RelaxNG. I now tried to take some Schematron rules of the old schema and put it in the new RelaxNG Schema to test if Schematron will work.

This is my "root" File which includes other RelaxNG Schemas:

<?xml version="1.0" encoding="UTF-8"?> <grammar xmlns="http://relaxng.org/ns/structure/1.0" xmlns:a="http://relaxng.org/ns/compatibility/annotations/1.0" xmlns:sch="http://www.ascc.net/xml/schematron" datatypeLibrary="http://www.w3.org/2001/XMLSchema-datatypes" ns="http://www.docscape.de/layoutV4.2">

<include href="layout_definitions.rng"/>

<sch:pattern> <sch:rule context="//Regel[@datensatz and @name]"> <sch:assert test="count(//Regel[@name=current()/@name and @datensatz=current()/@datensatz]) le 1">Die Regel »<sch:value-of select="@name"/>« zu dem Datensatz »<sch:value-of select="@datensatz"/>« ist mehrfach vorhanden.</sch:assert> </sch:rule> <sch:rule context="//Regel[@datensatz and not(@name)]"> <sch:assert test="count(//Regel[@datensatz=current()/@datensatz and not(@name)]) le 1">Die Regel zum Datensatz »<sch:value-of select="@datensatz"/>« ist mehrfach vorhanden.</sch:assert> </sch:rule> <sch:rule context="//Regel[@name and not(@datensatz)]"> <sch:assert test="count(//Regel[@name=current()/@name and not(@datensatz)]) le 1">Die Regel »<sch:value-of select="@name"/>« ist mehrfach vorhanden.</sch:assert> </sch:rule> <sch:rule context="//Zuweisung"> <sch:assert test="(//DefVariable[@name=current()/@name]) or exists(Name)">Variable »<sch:value-of select="@name"/>« nicht definiert.</sch:assert> </sch:rule> </sch:pattern> <start> <choice> <element name="Layout"> <optional> <attribute name="version"> <text/> </attribute> </optional> <optional><attribute name="datensatz"><text/></attribute></optional> <zeroOrMore> <interleave> <optional><ref name="g_Deklarationen"/></optional> <optional><ref name="g_Documentation"/></optional> <optional><ref name="x_Layoutinclude"/></optional> </interleave> </zeroOrMore> </element> <ref name="x_Layoutinclude"/> </choice> </start> </grammar>

The're is just no effect to the validation. The rest of the Schema works fine but the schematron rules have no effect. They seme to be ignored.

Any suggestions?

Thanks, Christian
