In pubsub, subscription items include and 'affiliation' attribute which is not in the schema

Removed attribute

Looks like this was a change between version 1.7 and 1.8 of the spec. Since the server is supposed to be 1.8 anyway, I will commit this patch.

Version 1.12 Subscription schemas

Namespace: http://jabber.org/protocol/pubsub#event
Schema:
<xs:element name='subscription'>
<xs:complexType>
<xs:simpleContent>
<xs:extension base='empty'>
<xs:attribute name='expiry' type='xs:dateTime' use='optional'/>
<xs:attribute name='jid' type='xs:string' use='required'/>
<xs:attribute name='node' type='xs:string' use='optional'/>
<xs:attribute name='subid' type='xs:string' use='optional'/>
<xs:attribute name='subscription' use='optional'>
<xs:simpleType>
<xs:restriction base='xs:NCName'>
<xs:enumeration value='none'/>
<xs:enumeration value='pending'/>
<xs:enumeration value='subscribed'/>
<xs:enumeration value='unconfigured'/>
</xs:restriction>
</xs:simpleType>
</xs:attribute>
</xs:extension>
</xs:simpleContent>
</xs:complexType>
</xs:element>

Was the attribute "affiliation" removed in the spec? If yes then this patch is fine by me.

Patch removes the offending attribute.
