Don't allow a POD to be created if it contains undefined variables.
Currently, a POD can be created that contains Tags which refer to variables defined in other Tags not included in the POD. Then those Tags fail when the POD is used in another template. Request that when a POD is saved, Report Designer checks whether there are undefined variables in any Tag, and if so, rejects saving the POD with a message like "POD contains undefined variables."
