This week I got to wondering: is it possible to write an XSLT program that
outputs an XSLT program and when the latter is run it outputs another XSLT
program? That is,

XSLT program #1 --> run --> outputs XSLT program #2 --> run --> outputs XSLT
program #3 --> run --> solves some problem

Is this even possible in XSLT? Have you ever done this? What types of problems
are suitable for this approach?
