Ah, this one again. The name attribute of <input> elements et. al. are NOT of
the datatype NAME, they are CDATA, and not subject to these rules.
If they were, you would not be able to legally use the square bracket suffixes
that PHP uses when you want the post/get data to come out as an array.
The restrictions are added by PHP, as historically the register_globals
behaviour meant that the data was mapped into PHP variables, so the names must
follow the PHP variable naming scheme, and are mangled by PHP to force them to
be so if they're not.
Some previous discussions:

The only places that NAME is actually used in HTML 4.01 (Transitional) is in
META for the http-equiv and name attributes, and the lang or hreflang
attributes on a few other elements.
