Hi All, 

The main updates in this version of the draft are:

* Significantly update descriptions for both AXoT and IXoT for message and connection handling taking into account previous specifications in more detail
* Add use of APLN and limitations on traffic on XoT connections. 
* Add new discussions of padding for both AXoT and IXoT
* Add text on SIG(0)
* Update security considerations
* Move multi-primary considerations to earlier as they are related to connection handling

Best regards

Sara.
