<DIV><FONT size=2 face=Arial>I noticed a behavior of an older OpenId library I'm

<DIV><FONT size=2 face=Arial>It gives openid.trust_root on the querystring, but
leaves the value empty. trust_root is optional, but so far it seems
everyone has interpreted that as "if you don't intend to include a value, don't
include the key." But this particular library does include the key and an
empty string for a value. Is this ok? </FONT></DIV></BODY></HTML>
