It is an error for the value of the match attribute to contain a
VariableReference.

Thanks. So, XMLSpy is telling me the true story and Xalan is kindly accepting my naive XSL!


I must say, I find this restriction somewhat amazing. I assume it's intended to reduce the complexity of writing XSL processors?

How do people normally write generic XSLT without using variables?

The only way I can see is to generate the XSLT on the fly, via an intermediate template, or code in another language, like Java.

Any suggestions as to the "right way" to do this sort of thing would be gratefully received. Feel free to point me to a book or website that discusses such things.

I'm loathe to use a non-standard feature, but since Xalan seems to be a very well-supported processor, I may just live with it, unless there's a standard approach that's vaguely clean to code.
