It looks like HTML 4.01 Strict is very useful. I noted the above points because I usually violate them, while at the same time, adding things which are not required. The DTD is relatively easy to read, and W3 has a link on their home page to validate any page you would like to test. But my old habits will be hard to overcome.
For instance, closing tags for LI and P are optional.
I'm still interested in the details of the choices for FORM.
Why did it need to be wrapped in a DIV? This doesn't appear to have anything to do with the requirements for Strict.
Another question is using a DIV to wrap the hidden inputs.
Are you providing a class for this DIV so that users can ensure that it doesn't contribute to any additional whitespace, indents or whatever? It seems like it would be helpful to have a generic class for this type of application.
I'll try to provide some additional examples.
