I think it's rather confusing to have both select element and "Select element".

I'm not sure if I should reference <code>select</code> in the <dfn> for this concept, and I didn't make all of the references to it do that either.

Should I do that instead? Or are there other places where I'm using <code>select</code> that should just be "select"?

"Content model:" should become the following.

    If the element has a label attribute and a value attribute: Nothing.
    If the element has a label: Text.
    If the element has no value attribute: Text.
    If the element has no label attribute and has a value attribute: Zero or more option element inner content elements.

Because the submitted value must be simply text, and "option element inner content elements" is only used to decorate label text.

I'm not sure I want to force authors to set a value attribute for simple cases like this:

<select>
  <option><svg>...</svg><span>Purple</span></option>
  <option><svg>...</svg><span>Green</span></option>
</select>

In this case, we can just use the text contents of the option, which would be "purple" and "green", just like we already do without the value attribute.

I suppose it would make sense to enforce that there is either a value attribute or some text node descendant of the option. Do you agree?

<select name="a">
<option value="2^2"><span>2<sup>2</sup></span></option>
<option value="square root of 3"><math><msqrt><mn>3</mn></msqrt></math></option>
</select>

In the above case, if there is no value attribute, the submitted value will be "22","3".

<select name="b">
<option value="female"><del>male</del>,<span>female</span></option>
<option value="male"><span>male</span>,<del>female</del></option>
</select>

In the above case, if there is no value attribute, the submitted value will be "male,female" regardless of which option is selected.

Because there are many cases like this, shouldn't it be enforce to specify the value attribute?
