I've just run into a weird quirk in IE where I had named form
elements like this: 2-some_name. IE was using just the numeric part as
an index in the form collection array. Boy, that took a while to figure out!
So, what are the rules for names and ids? I had thought this was
loosened up years ago.

This is relevant for ID attributes, but NAME attributes are CDATA
(except for the NAME attributes of META elements, which are NAME
tokens) and so the preceding section of - REC-html40/types.html -
defines their restrictions. ('2-some_name' may not be a viable ID but
it is a valid NAME).

Interesting that it doesn't allow []

Not in ID's, but for PHP luckily in name attributes it's allowed :)
From http://www.w3.org/TR/html4/strict.dtd:
.....
<!ELEMENT INPUT - O EMPTY -- form control -->
<!ATTLIST INPUT
%attrs; -- %coreattrs, %i18n, %events --
type %InputType; TEXT -- what kind of widget is needed --
name CDATA #IMPLIED -- submit as part of form --
.....
So, just CDATA in name attributes.

Oddly, in practice, it works the other way. All browsers I tested
recognized the number first for IDs, IE failed for number first for form
element name. Of course, IE's quirks are legion.
With that said, I'll rewrite my IDs for this particular app to conform.

Full ACK.
('2-some_name' may not be a viable ID but it is a valid NAME).
^^^^
I think you meant `name' in the sense of "value of the `name' attribute of
`form' elements or form controls" here, for the above definition makes it
very clear that ID and NAME tokens have the same restrictions.

It does not need to. Apparently you haven't been paying attention.

Not in *all* `name' attribute *values*, but in most, including those
relevant here.
