You have put your finger on the reason that XSLT is different from a
programming language. XSLT is not turing complete which means that there
are a variety of optimizations and checks that can be applied that are
impossible to provide in a programming language. It also means that XSL is
easier to learn than an XML-optimized programming language because the set
of concepts is much smaller than the combination of a programming language
AND a sophisticated XML parsing/searching/traversing library.

XML and XSLT both live on one side of the declarative/Turing-complete
fence. Scripting languages live on the other side. We need both.
