I just noticed that the Charting Plugin page utilizes several little icons like this:
Which are generated by this WML code:
Note that "(!)" represents *required*, "(-)" represents *not required* and "(+)" represents *conditional*
This is the first time I have seen these used... Are these listed in the documentation somewhere? Are there more of them? I would expect to see something like this listed in the "Plain Text Markup Help" pop-up
Good catch. They aren't, to my knowledge, documented. They should be. I'll work on that.
