We should probably make sure to update the wiki page to match and while we are at it I saw some other areas that should be updated in the wiki when this code goes in.

That was why I had put the extra comments in.  I just wanted to make sure we were aware of this before making this logger level look like a built-in level.

However, the precedent you are working with right now actually doesn't do that, and fax is listed right there with the other modules.  My suggestion for right now is to leave it as-is in your new patch.  I've already asked about separating the dynamic levels from the static levels (as well as describing the module that registers the level) in the sample and it's been approved, but I'll handle that in a separate patch.

That sounds like a plan!
