A general note - if you want to get a nodeset into a variable, and it
can be generated by a single XPath expression, then you can do this with

If you want to create a variable which contains a nodeset which can only
be generated with XSLT logic, then the short answer is you can't. But in
fact you can work round this if you need to badly enough by using
parameters instead, typically building up the contents of a parameter by
recursive calls until it is complete, and then calling the next stage in
your transform with your complete value as an input parameter.
