*And* where it is used. A wfMsg() function echoed to the screen would 
accept html (very bad), passed to Html::element, would be plaintext, and 
passed to the parser in a recursive invocation by a tag extension, would 
accept wikitext.

I don't think it is feasible to automatically determine which kind of 
output is accepted by a given message, despite of it being really cool.

Well, it's not completely useless :) and sure it was a practical exercise.
