Re: AW: Restricting attribute content to not include a specific string

Hi Roman,

oXygen does that :). It chains internally (in a single operation) the 
validation with XML Schema using Xerces and the extraction of Schematron 
rules followed by a validation with the Schematron XSLT implementation 
of the document against the extracted rules. I suppose the same thing 
can be easily done also with ant if you are looking to integrate this is 
a script.
In oXygen if you associate the XML Schema with Schematron embedded rules 
externally then for schema type choose XML Schema with Schematron 
embedded rules and if you associate the schema inside the document using 
the schema instance attributes then you need to use also the oXygen PI 
to associate the same schema file as a Schematron schema, thus the 
oXygen validate action will perform both validation in one step.
Note that oXygen supports both XPath 1.0 and XPath 2.0 for Schematron 
XPath expressions. If you want to use XPath 2.0 from a script then you 
need to modify the stylesheet that extracts the rules to generate a 2.0 
XSLT stylesheet and then use an XSLT 2.0 processor like Saxon 8 for 
instance.

Best Regards,
George
