Example 9, 10.

The 'b' attribute indicates the last stanza received.  Both parties can send 
this attribute, although in the example the client does not send it for some 
reason.  This is enough information to know what was not received by the 
other party, and the stanzas can be re-sent.

It is not mentioned in the XEP, but the client should probably be required to 
bind to the same resource again, when using resume.
