Requiring selection with cfform and cfselect

Question

I would like to have CF enforce the required="yes" attrribute
of the cfselect tag as the documentation says it should. I've seen
this discussed before here, but no resolution. The documentation of
the required parameter says:
============ quoted text ============================
* Yes: a list element must be selected when the form is
submitted.
Note: This attribute has no effect if you omit the size
attribute or set it to 1, because the browser always submits the
displayed item. You can work around this issue: format forms by
having an initial option tag with value=" " (note the space
character between the quotation marks).
============ end quoted text =========================
Yet it does not work. I can use additional javascripts,
validate on server side, etc., but I would like it to work as the
documentation says. Or to know why the documentation continues to
say it will work, if it won't.
Thanks!

Try putting in the closing tag
<option value=" "> </option>
