XML validation-Schematron

Question

Hi All,
I validated a XML document using Schematron validation, but its not throwing  any errors if there is any mismatch between source document and validation document.
Source Structure:
OrderStats     1
   Order          1...unbounded
     id
     value
id and value are attributes of Order
Validation Code:
<?xml version='1.0'?>
<schema xmlns="http://www.ascc.net/xml/schematron">
<title>OrderStats Schema</title>
<ns uri="http://applicon.dk/teched/06/tns" prefix="ns0"/>
<pattern name="Root">
<rule context="ns0:OrderStats">
<assert test="Order">No Orders</assert>
</rule>
</pattern>
<pattern name ="Order">
<rule context="Order">
<assert test="@id">No Order id</assert>
<assert test="@val">No Order Value</assert>
</rule>
</pattern>
</schema>
I used XSLT mapping, in that i called this Validation template..but if the source document contains wrong tag names or incorrect value it should throw some error..but i am not getting any error based on validation code..
Can anyone suggest some solution for this type of validation

Hi there,
as far as I know there is no integrated Schematron validator neither in XI noch in the Netweaver Application Server.
I'm using an XSLT implementation for schematron: The XSLT programm http://xml.ascc.net/schematron/1.5/skeleton1-5.xsl transforms a schematron schema to an XSLT program, which can validate any XML document according to the schematron schema.
You can read it in my blog: /people/tobias.trapp/blog/2006/08/22/xml-processing-in-abap-part-8--using-xslt-for-validation .
Of course there are Schematron Java APIs, for example  http://www2.informatik.hu-berlin.de/~obecker/SchematronAPI/ but I think it is still incomplete.
I'm using a simple XML editor to create schematron schemas. If you have further questions about tools like Stylus Studio I recommend to ask them on a special mailing list.
Cheers
Tobias
