Re: [xsl] Does XSLT have a run-time system?

AFAIR, The .NET XslCompiledTransform XSLT processor does have a
runtime system -- a library of commonly needed functionality to run
the transformation.

Hi Folks,

Wikipedia describes "run-time system" like so [1]:

        Every computer language implements some form
        of runtime system, whether the language is a compiled
        language or an interpreted language.

        As a simple example of a basic runtime, the runtime
        system of the C language is a particular set of instructions
        inserted into the executable image by the compiler.
        Among other things, these instructions manage the
        processor stack, create space for local variables, and
        copy function-call parameters onto the top of the stack.
        The reason this behavior is part of the runtime, as opposed
        to part of a keyword of the language, is that it is systematic,
        maintaining the state of the stack throughout a program's
        execution. The systematic behavior implements the execution
        model of the language, as opposed to implementing semantics
        that contribute to a particular computed result.

From that description, run-time doesn't seem to be pertinent to an XSLT 
processor implemented using, say, Java. Those kinds of 
execution-time-inserted instructions would be done by Java (or at a lower 
level), I would think.

Does XSLT have a run-time system? If yes, would you give some intuitions 
about what it contains please?
