It would have the same effect: code using this function could not be easily
converted to be part of a stylesheet that processes a collection of
documents.

I have occasionally wondered whether the ban on using tunnel parameters inside
a function is perhaps rather paternalistic. In many ways, accessing tunnel
parameters is "less evil" than accessing global variables, so if functions are
allowed to do the latter, they should allowed to do the former. Code that
binds the current document to a tunnel parameter is more adaptable and
reusable than code that binds it to a global variable.
