Re: Validation via Schematron

The Algo WG is attemting to create a markup to describe the parameters of an algorithmic trading screen. OMS providers would code their systems so that they could import an XML instance and render their order entry screens based on the info in that instance. If this could be accomplished then the OMS provider would never need to create a new release just to support the latest algorithm. The ideal workflow would be:
1. Algo provider creates an XML file that describes the parameters of an algorithm (parameter name, type, fix tag, , preferred GUI component, default value, ...)
2. XML file is sent to OMS providers (or directly to OMS users) where it is imported into their systems.
3. Clients log onto their OMS - and Viola! The have a new algorithm to use. No upgrade was needed because the OMS renders the screen on-the-fly.
At this time we are researching how the values entered by the OMS user can be validated. We want to include validation instructions within the XML file. Schematron seems to work very well for this purpose. Using a Java Transformer object I can easily check the validity in only a few lines of code. But from what I've read, CLiX provides more capabilities than schematron. So I'd like to explore it in more detail.
Can anyone tell me how I can programmatically perform a CLiX validation? Does it follow the XSL tranform model as schematron does or does it require an API? And if I need an API what are my options?
Thanks for all the help so far.
Cheers.
-Greg
