Answer 1

If your processor does not support the EXSLT math:random() function, then you can:

1. check the documentation to see if the processor provides extension functions under a different namespace;
2. write your own extension function using the extension mechanism provided by your processor;
3. supply a random number to the stylesheet as a parameter at runtime;
4. derive a random number from the current date/time (if your processor can generate those, or if you can pass them to the stylesheet at runtime) or from some other non-constant data, for example the length of the processed document (knowing the purpose would be helpful here);
5. get a random number from a web service.
