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

["Costello, Roger L." <costello@xxxxxxxxx>]

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.
