Re: [xml-dev] Recommended way to extend Schematron?

[George Cristian Bina <george@oxygenxml.com>]

Hi Roger,

Here there are a couple of additional possibilities:

Skeleton and also our oXygen's Skeleton-based Schematron implementation 
have a parameter that allows foreign elements - that can be used to pass 
over XSLT code from your Schematron file to the generated stylesheet, 
for example if you define an xsl:function then that will go in the 
generated XSLT code and you should be able to call that from your XPath 
expressions.

Another option will be to handle a new queryBinding in the Schematron 
implementation that you use, for example the value for that can be xslt3 
to indicate that you want to use that and then you can access functions 
that are defined in XSLT 3.

Best Regards,
George
