Re: XHTML 1.1 modularization last call: basic tables module

Another issue in the legacy module, it has notes about anything
requiring specific modules, like <input> only with either forms
or basic forms.

For consisteny it should say that a <caption> is only possible
with the tables module.  Putting it together that results in:

1 - add "tables mdule" to the note about <caption>
2 - add "or basic tables module" to the note about <table>
3 - ditto for <tr>, <th>, <td>.
