I thought about the other options (multiple groups, is_visible, and bin_attrs), but those are almost all not the "normal" usage, so I figure it's worth the extra 6 lines of text if you want to support is_visible or binary attributes.
After converting all of the class code to use groups, it seems to match up with the defaults, but if in the future it's more popular than expected, I'll gladly add it.
