    Using tags to modify parameters

This Revit Architecture 2009 video tutorial covers how to use tags as drivers for parameters rather than just for display.  The idea here is to use "working tags". The Tags can easily be cleaned up for display on working drawings later, the intent here is to avoid having to go to the properties of an object to change parameters.   Here is a link to the source files on the forum.
