Not at all. The passed nodeset may contain elements with arbitrary
names. you get access to whatever parameter you need with something
like this:

  $pEnvironment[name() = 'myparamName']

In case you don't want the parameter name ('myparamName') fixed in the
stylesheet, it itself may be passed as a parameter to the stylesheet.

One way to implement dynamically created variables (such as in a
simple calculator) is described here:
