Well it's not really our problem if Internet Explorer doesn't adhere to the
XHTML specification, but how could the <optgroup> element be used to provide a
workaround?

You have however only one indent level and it can be used in the folowing way:
<optgroup label="GNU licenses">
<option ...>
<option ...>
</optgroup>

Firefox is a better browser but the reality is that Internet Explorer is the
most used browser.

Quick survey of <option disabled="disabled"> on Special:Upload

• IE 6.0 on XPSP2: ignored
• Safari 2.0.1: ignored
• IE 5.2/Mac (OS X): disabled works, but the indented entries don't show in the pop-up
• IE 5.0/Mac (Classic): works
• Firefox 1.0.6: works
• Opera 8.02: works

Yup, another bug in IE, hooray. But seeing as nested groups aren't really
required here, the <optgroup> tag would be the best solution. Note that "all
OPTGROUP elements must be specified directly within a SELECT element (i.e.,
groups may not be nested).", but they do auto indent the groups and emphasise
the labels (in IE as well).

But more useful than not having them.

I don't know if it's intentional, but the nested groups don't do anything at the
moment. Everything is just indented by one level, which is acceptable.

I think, a lot of nested groups which are also selectable by the most users,
are very confusing for especially new users. So, a lot of uploads on the Dutch
Wikipedia since there is the license-selector haven't the just license or no
license at all.

It must be impossible to upload a file without selecting a license, also
the 'none selected' option should not be selectable or there must be a template
like {{Unknown}} assigned to.

This is offtopic for this bug, but to reply to the previous comment: we quite
deliberately *do not* block uploads with the no license option, since the
most likely alternative is a lot of absolutely totally 100% non-free material
getting uploaded with false license information because people just click
whatever lets it go through. Then it's harder to track down and delete them.

To suggest alternative behavior, please open a new bug rather than commenting
further here.

I've added a CSS style which makes the disabled items show grayed-out correctly in MSIE/Windows.

Additionally, a JavaScript hack will revert the selector to "None selected" if you actually select one of the disabled items.
There might be further improvements which can be made here.

Safari still doesn't show the disabled items as gray, but the hack to prevent them from being selected is there, and
should be at least a bit of a cue to users that their selection didn't take.

Another JavaScript hack seems to fix the display problem in MSIE/Mac. (Setting the option text to itself... oh what a
lovely bug!)

I guess this should have been set to FIXED?
