I like the idea of a single 'base format' which can be used to drive
the validation and the form layout too.

Is your scheme a format which, when rendered as html, defines the form
and, when parsed appropriately, provides the form validation too?

As in:
<form>
 <input type="text" id="abc" format="integer" /><br />
 <input type="submit" />
</form>
