Barry,
Correct. If you do not specify the ADP template when you call ad_return_template, it looks for an adp with the saem filename as the tcl file.
You can specify an alternate template, or decide in the tcl code which template to call.
But it sounds like you are talking about replacing the built-in templates with locally customized versions. Is this what you are referring to? There isn't currently any built in way to tell the request processor to use a local version of a file instead of the default one supplied with a package. I have a couple of different ideas on how to fix this to make it easier to make local changes to packages.
