Hi Eugene,

What you want to do is possible in another way by using a template
reference to a template (that must match the reference and need not be
named).

This approach is in the base of the whole XSLT 1.0 functional
programming library FXSL. 

A number of articles about FXSL and functional programming in XSLT 1.0
are available at:

http://fxsl.sourceforge.net

I'd recommend specifically the first and second article (in that
order), which introduce the most basic concepts of higher-order
functions and provide the implementation of the most generic design
patterns -- folds (primitive recursion) over lists, strings and trees,
maps, iteration, currying and partial application.

The FXSL library contains useful functions for:

  - calculating various math functions and their inverse (e.g.
trigonometric, hyperb.trigonometric, exponential, logarithmic,... etc)
and for solving equations of one real variable, numerical
differentiation and integration.

  - random number generator, generating numbers according to
pre-defined distribution, randomising a list.

  - various text-processing -- tokenizing, text justification, spelling
checking/correction and generation of close words.

The FXSL library has three different editions, which support MSXML,
XALAN and SAXON. It can be downloaded at:

http://sourceforge.net/projects/fxsl/
