Error handling extension for XSLT 2.0

I finally wrote a few words about the try/catch extension I wrote for Saxon a couple of months ago (see this and this entries). You can find the project page there: http://www.fgeorges.org/xslt/error-safe/.

I also wrote a first draft of a specification for such an extension. There are some differences between this and the actual implementation for Saxon, but the spirit remains the same. It can be found there: http://www.fgeorges.org/xslt/error-safe/error-safe.html.

I don't know if the EXSLT project is open to extensions for XSLT 2.0. I think that would be worth having an error handling extension defined in such a vendor-neutral project. I'm indeed interested in any comments about this extension and its specification.

I've found out that org.fgeorges.exslt2.saxon.CurrentError class is not thread aware, as you're using static variable to track exception stack (for all threads).

I guess you need to add XPathContext to you functions as first argument, and store your data in Controller's user data.

Hi Vladimir,

Yes you're right. I was not happy with the fact that CurrentError was using static stuff. But I never took the time to think about it.

Thanks for the hint, at first glance that seems to be the right way!
