This is according to the HTML 4.01 specification, which says:
"When a form is submitted for processing, [...] controls have
their name paired with their current value and these pairs
are submitted with the form."
This also applies to XHTML 1.0 -- indeed, the XHTML 1.0 Strict DTD says that the name=
attribute is *required* for all <input > types except submit and reset.
None of this is likely to change in the foreseeable future -- name= will always be the
one to use for submitted form elements.
The id= attribute is for identifying a particular element uniquely within the [X]HTML
document -- no two elements can have the same id= attribute. Its most likely uses are
for specifically targeted stylesheet formatting, or manipulating a specific element
using a client-side technology such as JavaScript. It is absolutely *not* a
substitute for name= in form elements.
Hope this clears things up a bit for you.
Cheers!
