Thank you Michael and Abel. I got it working with 2.0. I think I will
start using XSLT 2.0.
The infinite loop solved when I gave a default value for the
parameter, very novice to XSLT to know why, but its working now.

Can I pass parameters like this.
Calling_Point => A_Named_Template, do apply-templates => {One or more

I tried to do this by passing parameters along with apply-templates,
and then passing it again from all matched templates to a named
template where I finally need it, it ended up in infinite loop. When I
just taken out the parameter passing and used global variables it
worked fine.
That you turned into an infinite loop has to do with a bug in your
programming logic, not the passing itself. And probably you mean that the
recursion went too deeply nested (but this may feel like a "loop"). In XSLT
1.0, the method of programming is certainly viable. But as soon as a new
step is required between one and another template, you must remember to pass
on the parameters again (which can become a maintenance nightmare)
What you are after is what Michael Kay suggested: the XSLT 2.0 feature of
tunneling parameters which can be defined once and will be passed on until
it matches a template that defines these parameters (where you must also
specify that they are tunneled).
If you have to stick to XSLT 1.0, using global parameters may be the
easiest way to go. If you want to modularize or "hide" the variables, you
can use an imported stylesheet which defines its own "global" parameters
(variables).
