Hi David,

We plan to add ISO Schematron support - hopefully it will be ready to go in the next oXygen release.

Excellent. Eric van der Vlist's new book doesn't have a list of applications with a Schematron implementation, but one of his schema examples includes an <?oxygen RNGSchema> processing instruction.

A question not entirely unrelated to supporting ISO Schematron: Does anyone have tips on using Schematron on namespaced documents in the current oXygen implementation (8.1)? I can't get it to work -- I even have documents with mixed namespaces. (I've tried binding namespaces both at the top of the Schematron and on the element where the namespaced XPath appears.) For any guidance, I'd be grateful. Cheers, Wendell At 03:34 PM 4/2/2007, you wrote:

Let me add my vote for this; I need to use <sch:let> in my schemas, and currently Oxygen doesn't recognize it. Lars

Hello, Check out the sample schemas Tournament.xsd and Tournament.rng in the schematron folder of the sample.xpr project located in [oXygen-install-folder]/samples. They show how to embed Schematron constraints in an XML Schema or RELAX NG schema. The <?oxygen SCHSchema="..."?> processing instruction is necessary for checking the validated XML instance against the Schematron constraints and it will be inserted automatically in the instance by the "Associate Schema" action if you enable the "Embedded Schematron rules" option in the Associate Schema dialog. Only Schematron 1.5 is supported in the current version, that is oXygen version 8.1. This is why you will see only the "http://www.ascc.net/xml/schematron" namespace in these schemas. We plan to support also ISO schematron starting with version 8.2 which will be released in less than a month. Regards, Sorin Gary Gapinski wrote:

http://xml.garygapinski.com/XCCDF/xccdf-1.1-ext.xsd was my first fling with Schematron, and operates on documents with multiple namespaces. While validations are resource-intensive, they do work.

One does need a processing instruction in the document to be validated (<?oxygen SCHSchema="..."?>) to enable Schematron constraint processing. This is added if the "Embedded schematron rules" check box is checked in the schema association dialog.

Gary
