Hi Jeff,
Stylus Studio detects possible infinite loop when the same template has
been invoked more then one time with the same parameters. This is a
warning and not an error, If you want you can turn it off
(Tools->Options->XSLT Editor->XSLT Settings).
The infinite loop detection avoid to hang the processor compare to other
applications that freeze forever.
