FXSL (a function/template library implementing HOF in XSLT and written
in pure XSLT)  implements:

Math functions:

Random number generators:
    http://fxsl.sourceforge.net/articles/Random/Casting%20the%20Dice%20with%20FXSL-htm.htm

Higher-order functions, currying/partial application, etc...:

A good example of the math capabilities of FXSL for XSLT 2.0 was
recently provided at:
