Hi,

I'm trying to validate a date by using castable in a schematron file:

<?xml version="1.0" encoding="UTF-8"?>

<schema xmlns="http://purl.oclc.org/dsdl/schematron" xmlns:xs="http://www.w3.org/2001/XMLSchema">

	<pattern>

		<rule context="//meta[@name='OVERHEIDop.einddatum']">

			<assert test="@content castable as xs:date">Geen juiste datum</assert>

		</rule>

	</pattern>

</schema>

I can transform this sch file to an XSLT with the ISO iso_svrl_for_xslt2.xsl stylesheet, and then use the result to validate a document. So it seems the above sch file is OK.

However, trying to apply the above .sch file directly to the same example XML document in Oxygen 11.2 Professional returns a warning:

SystemID: /Users/matthijs/Dropbox/werk/nieuwe_opzet/metadata/code/genereer_schematron/test_juni_2012/castable_test.sch
Engine-naam: ISO Schematron
Ernst: warning
Omschrijving: Error in expression @content castable as xs Unexpected token <name> beyond end of expression

And ultimately a fatal error.

It is a bit of a hassle to not be able to use Oxygen for quick debugging of sch files.

Any thoughts how to solve this?

Hello,

You are using "castable as" which is only available in XSLT/XPath 2.0. To make this work, you have to specify on the schema root the attribute:
queryBinding="xslt2"

Thanks Adrian, this solves the problem.
