[JDEV] unregister

[Amit Dev]

As an amateur jabber client programmer, i have
a small problem.
I'm using jabberv1.0

I registered a user, saved his key and send his
key for unregister. The following is what i send.

<iq type='set' to='oblivious' id='1001'>
<query xmlns='jabber:iq:register'>
<remove/>
<key>1ba24fa8133ec0000da9e97901c45e3bc8a91a4f</key>
</query> </iq>

I'm getting the following error msg as result.

<iq type='error' to='oblivious' id='1001' from='oblivious'>
<query xmlns='jabber:iq:register'>
<remove/>
<key>1ba24fa8133ec0000da9e97901c45e3bc8a91a4f</key>
</query> <error code='406'>Not Acceptable</error></iq>

Can anybody help me ?

BTW: the id attribute value was supplied by me. Does
it signify anything?
