John,

> whether you are also considering support for "type library" schematron validation.

Mainly I'm thinking of validating against a set of rules that are over-and-above those defined in an XML Schema. Business rules more than general structural/grammar validation but I hadn't really considered the notion of 'type libraries'. Although we can do a lot of these kinds of things using XForms' MIPs I was looking at how we can bring in and apply external business rules.

Hi Philip,

Just curious whether you are considering only "full" schematron validation, or whether you are also considering support for "type library" schematron validation.
A type library provides datatype definitions that can be applied to instance data nodes via the type MIP (model item property).
It's probably no big deal if an implementation already provides an XML schema way of building type libraries, but like I said ... just curious.

________________________________



I have been experimenting with demonstrating Schematron validation within XForms by the use of the proposed transform function. I have been using XSLTForms beta3 and have a rather limited example which uses the textual result from the XSLT 1.0 skeleton implementation. Seeing as XSLTForms' transform function returns a string serialization of the result of the transform I cannot use the SVRL representation of a Schematron report which would, if available as an XML tree, provide more options for presentation and logic/behavior than the basic text report. However, it does prove that it can work all be it that the 'complied' schema can only be accessed via a URI.

I am still looking for an implementation that'll firstly let me store the compiled schema in an XForms instance and ultimately allow me to daisy-chain the compilation transforms, across an number of instances, so that I can create a Schematron rules editor in XForms and have the schema compiled and applied to a test source document upon DOMSubtreeModified events dispatched from the schema instance. The nearest option I can currently see working is to use Orbeon's xxforms:call-xpl() function and implement the Schematron compilation pipeline externally to XForms but that's not what I'm after.

I have attached the fledgling form so that you can see the string of instances I'll in order to compile the schema. It's all rather a hack at the moment but I'm planning on making it look a bit more presentable.
