Thanks for the patch! I've incorporated it and made some small changes,
as noted below.

First thing I need was HTML5 attributes 'required' and 'autofocus' for input
fields. Those changes are located in basis.urs and are rather straightforward.
I've changed both to be type [bool] instead of [string], and I added an
Ur/Web parsing extension to allow the usual HTML syntax, without having
to provide a value for the attribute.
I also undid your addition of attribute 'value' for checkboxes. That
attribute breaks the Ur/Web abstraction of a checkbox as generating a
Boolean value; it's nonsensical to allow assigning a string value. Some
real-world use cases of checkbox 'value' might come from having multiple
checkboxes in one form with the same name, but the Ur/Web standard
library currently rules out duplicate checkbox names at compile time!
The second thing is the <input type='email'/>. My intuition says me that adding
custom input types was not designed to be regular operation, but building recent
HTML5 pages may require doing it. Quick search [2] shows that there are 'url'
'tel', 'search', 'number', 'range', 'date', etc. I included the monoize.sml
change to support just the [email] for ordinary [formTags]. Is it possible to
prepare a procedure of doing the same thing for [cformTags] (references to
javaScript confuse me)?
I've now added old-school and AJAX versions of all the new HTML5 widgets
that I learned about. I'll be interested to know what you think of the
interface.
