Proposed revision:

An XP sender (not necessarily the initial XP sender) wants the XP message 
to be handled with specific quality of service as it traverses the XP 
message path to include multiple XP Processing intermediaries.  Information 
in the XP message is used to select appropriate QoS mechanisms (e.g., RSVP 
[1], Diffserv [2], MPLS [3] , etc.).  Selection of QoS may be constrained 
by QoS policies [4], Service Level Agreements (SLAs) [5], Service Level 
Specifications (SLS) [6].

Previous version:
An XP Processing Intermediary on the edge of a public network may add XP 
Blocks and handle interfaces to lower layer QoS mechanisms (e.g., RSVP, 
MPLS, DiffServ, COPS Policy info, etc.) for the next hop in the message 
path to the next XP Processing Intermediary.  An XP Block may provide 
information used by the XP Processing Intermediary to determine what QoS to 
select, what Service Level Agreements (SLAs) and what service level 
specifications (SLSs) [6] may apply.
