Couple thoughts:

1.  I think I would have one link to the html5 stuff and a brief explanation to the method to our madness on the field types and validator attributes we have chosen. I would use an asterisk and footnote on our own generic types (and maybe a reference about how used or why, e.g. boolean would be checkbox for html, etc.).

2. I would define the validator attributes first and then just have simple list of validators under each field type vs. nesting descriptions of the validators under any of the field types.

3. I would bump this whole section up above the examples section.
