In this, Michael, I would be pleased to be proved wrong! That's even with Saxon 8.0 which so far only does run-time validation against the schema, it doesn't yet do any compile-time checking (that's next on my list). Kewl! The difference basically is that instead of producing incorrect output, which then fails validation at the next stage in the pipeline (the FO processor in this case), you get an error message pointing to the XSLT instruction that produces the invalid output, which gives you a much faster cycle to correct the error. Yes ... may I suggest (and you've probably thought of this) to make it fully switchable? That way during development I incur the processing time to make sure everything works as I'm writing my stylesheet, but then when I'm confident that my stylesheet is working turn it off ... when something is (thought to be) working, I'd like to just use the XSL-FO processor as a safety net and pass through my transformation quickly without schema validation to get results quickly with the (hopefully warranted) confidence there isn't a problem lurking in my stylesheet that was not caught during testing. A shameless plug for my product, I know, but I really have found that it makes a difference. Not at all, Michael .. worthy of discussion ... I'm looking forward to seeing how new tools change my day-to-day XSL-FO development for my customers. Following this enquiry, I will now be looking out for an opportunity to try it out on a stylesheet that produces XSL-FO output. But won't you need an XSL-FO schema, then? I'm not sure one exists ... unless, perhaps, one took the RenderX DTD to Trang and then tweaked the result.. Thanks for bringing this up, Michael. ....................
