Allison,
My experience has been that the help files, and especially the ones relating to styles and code that can be used, have a convoluted labyrinth of internconnections that make navigation more like a scavenger hunt, and also have many instances of conflicting information on different pages in the set, which is not necessarily accurate for what is and is not supported here.
It is my guess that you have just documented another one in the long list of such differences between information on help pages and reality.
