thanks, Brett
In Examples 11-13, and 15, 16 (and 14 if you meant to have the original
XML there too) of http://xmpp.org/extensions/xep-0248.html , there is no
<field var='FORM_TYPE' type='hidden'>, whereas the other examples with a
child <x xmlns='jabber:x:data'/> in <configure/> have it. If it is not
to be there, when is it and when is it not needed?
