While testing aTalk, trying to remove a roster entry using the method below:



Note: the entry is still pending subscription authorization from the contact.


Smack 4.2.0 sends an <query xmlns='jabber:iq:roster'> with 'ask' attribute in <item/> which is not allow as per RFC6121 document


================ RFC6121 section extraction =================  Ask Attribute

   The 'ask' attribute of the <item/> element with a value of

   "subscribe" is used to signal various subscription sub-states that

   include a "Pending Out" aspect as described under Section 3.1.2.


   A server SHOULD include the 'ask' attribute to inform the client of

   "Pending Out" sub-states.  A client MUST NOT include the 'ask'

   attribute in the roster sets it sends to the server, but instead MUST

   use presence stanzas of type "subscribe" and "unsubscribe" to manage

   such sub-states as described under Section 3.1.2.
