This only proves that the site works, it doesn't explain why/how.
What does alert(""+document.myname) show?
And document.myname[0].nodeName, and with [1] ?
(to see if it behaves as an array AND as a normal element too)

So you get a list of two forms in that case....

That's a VERY broad statement, which would need further testing with other
kind of elements.

- From the above one could also conclude that "document.formname" first looks
at forms (and returns only forms, if it found any). The reason I'm tempted to
believe in this "exception" is that document.formname is already an exception:
we (and IE) look for that before looking for JS properties that have been
set in the document. What I mean is (with the above <form> tag assumed) :
document.myname = 'foo';
alert(document.myname);  << will still return the FORM object, not 'foo'.
But this only happens with forms and images apparently. The other cases
of document.myname lookup are done after the JS property lookup.
