Overall, I vote we roll back this change.

We support HTML on output just fine.  This is actually a tag design issue.
We aren't really either HTML or XHTML (for example, we camel case the
JavaScript event names for readability).  In this case, we simply require
all enums to be lower case across the whole API set.  The end result is that
we will always output legal HTML or XHTML, but the tags are not HTML or
XHTML.  We are a higher level abstraction.

It might be pointed out that the restriction to lower case is also correct
in HTML, it's a subset of the valid values because SGML doesn't enforce
casing on either elements or enums.  So you can make the argument that we
should support <netui:HTML> and <netui:HtMl> etc.

I'm not sure if we enforce all of these but:
the checked, disabled, selected and readonly flags, would need to be looked
if we expose any of the input "type" fields, button may do this

I guess there aren't too many of them beyond the form.

Thanks again for the feedback Daryl. I'm good with your suggestion, and
