Hello, We're adding flow rate control support for IBB since our application makes heavy use of file transfers. Since we need to receive ACKs for packets, we're using <iq> for data transport, according to XEP-0047. The first problem is that the algorithm we're using needs to know the sequence number of the packet being acknowledged. But, according to the XEP, it is not allowed to include any inner XML stanza on the <iq> of type RESULT used as ACK:
<iq from='[EMAIL PROTECTED]/balcony' to='[EMAIL PROTECTED]/orchard' type='result' id='ibb1'/> What would be the best way of including this information in the ACK? Should we use <message> + AMP for having that info? Thank you, William
