looks fine! i thought it would produce something like :
 <option selected="True" value="ACCEPTED">ACCEPTED</option>
                   ^^^^
though i had never tried it before...

as i looked at TALInterpreter.py, obviously 'selected' is one of a handful
of html attributes that get special treatment...

line 33:
BOOLEAN_HTML_ATTRS = [
    # List of Boolean attributes in HTML that should be rendered in #
minimized form (e.g. <img ismap> rather than <img ismap="">) # From
http://www.w3.org/TR/xhtml1/#guidelines (C.10)
    # XXX The problem with this is that this is not valid XML and
    # can't be parsed back!
    "compact", "nowrap", "ismap", "declare", "noshade", "checked",
"disabled", "readonly", "multiple", "selected", "noresize",
    "defer"
]
