Why doesn't a SELECT element's innerHTML reflected which option was
selected? Works in IE. I need this functionality so that I can retain
what choices a user made in a tabbed interface.

Yes, they certainly can.
<form action="" name="foo"><p></p></form>
<form action="" name="foo"><p></p></form>
is perfectly Valid HTML 4.01 (Strict!).
Based on what criteria? [...]
The HTML 4.01 Specification.
Different `form' elements in one HTML document may of course have
the same value for the `name' attribute or short: the same name.
In the element of the `document.forms ' collection and the value
returned by the HTMLDocument.ge tElementsByName () method, they then
make up an collection of their own.
In the latter, yes. In the former, no. Neither Mozilla (including
recent Firefox releases), Netscape, nor Opera versions prior to 7.11
(possibly earlier, but definitely later than 7.03) return a
collection from the forms collection.
Yes, indeed. And the namedItem() method of the HTMLCollection
interface does not require them to. D'oh.
And when you think about it: not allowing the same name for
different elements would render the getElementsByTa gName() method
of the W3C DOM's HTMLDocument interface redundant.
What's the getElementsByTa gName method got to do with this?
Nothing, repeated typo.
As for getElementsByNa me, the answer there is actually quite simple:
the HTMLCollection interface is only meant to return single
Node-implementing objects via the item and namedItem methods (and the
property accessor equivalents). That browsers return a collection is
a product of DOM 0, not DOM 1 or 2. As such, the getElementsByNa me
method was meant to fill this void.
Of course, I'm not, nor have I been, a member of the HTML or DOM
Working Groups, so this is just my interpretation of events.
You're probably right.

[Referring to getElementsByTa gName, not getElementsByNa me] Oh my, yes of course! :) Sorry for causing confusion.
Given the poor state of mind I was in yesterday (I've had sleep now.
Yay! :D), you certainly did confuse me. You're forgiven, though. :p
[Retaining the name attribute in XHTML]
No, in XHTML 1.0 _Strict_, the following elements do have the `name'
attribute:
meta, a, object, param, map, input, select, textarea, button.
Only four of them can be considered form elements.
Five, I believe. The OBJECT element can also participate in form
submissions, however the specification doesn't define how this
particular mechanism works which is verging on ridiculous. Still, it is
a form control and retains its name attribute for this purpose.

I meant regarding the value of that OBJECT element. In both 17.2 and
17.12.2, the specification says that the value "is determined by the
object's implementation" .
The description in 17.2 goes on to say:
"... (i.e., it lies outside the scope of this specification). "

ISTM that having the `object' element as a descendent of the `form'
element and submitting the form it creates would submit the data of
the resource that the `object' element refers to which is referred
to as the `object' element's value. That would allow for submitting
any form of information if the UA provided means to display it. Of
course the way how the UA displays it (e.g. what plugin is used and
what parameters it needs) would lie outside the scope of the HTML
4.01 Specification.
