The only variables you can share across XSLT stylesheet modules are global
variables. Global variables have a single value that is constant for the
whole transformation. The variables above have a different value each time
the template rule is instantiated, because they are defined relatively to
the <programme> element.

As David pointed out, there is very little point defining these variables.
All it does is enable you to write $exp-date instead of exp-date, which
gives you neither an improvement in stylesheet legibility nor an improvement
in performance.
