IMHO that is easy: initial value of "h" should be 0 (not 1 as some
suggested), incremented with each stanza processed. So the ACK after the
first stanza would have h="1". After 2^32 stanzas it would be 0 again,
than 1, etc.
Usually you won't see h="0", unless no stanza was processed by the
far end before first <r/> was sent, or when stream is resumed when it
was broken before any stanza has been processed.

Greets,
