I don't think so. Whatever output you require for the UserTag should be
parsed and presented. Maybe you want to generate the "table" output within
the function (given input parameters) and then output it to the page. i.e.
One tag.

Maybe you are not putting a sub within a sub i.e.. Think of the UserTag sub
as a program, the recursive function is a subroutine within it. Shouldn't be
anything wrong with that. It's legal in Perl.
