BACK     Known issue: Element names containing "[" and "]"

It is expected that all element names only contain letters, digits and underscores. Also, you must ensure that no two non-radio/non-checkbox elements have the same name. Not following these rules may cause unpredictable behavior.

I've not verified this, although the concept seems to be a valid one. Anyone have experience with this? A truly working example would be helpful. Thanks.
