Yes, there was.  It's fine when generating interactive help docs in the CLI but when I started generating the full documentation set for HTML, the handlers were getting re-registered over and over again and each time a new one got registered, you got duplicate data in the generated documentation.

I originally tried to use the unique ID you added but ran into a problem with that, too.  I can't remember now what the issue was but I'll try to do that again and see what the issue was.
