This update attempts to address all of the open tickets.  A summary of changes is below.  Please provide feedback on these changes.  Thanks.

111:
- We have not received any other comments from the WG on this matter.  As a result, no action will be taken.

113:
- We have not received any other comments from the WG on this matter.  As a result, no action will be taken.

127:
- Updated Section 1 to add RFC 3903 (PIM-DM) and RFC 4601 (PIM-SM) as citations for "traditional IPv6 multicast routing and forwarding."
- Updated Section 5.5 "worst-case link-layer latency" to "expected link-layer latency".
- Updated Section 5.5 default value for DATA_MESSAGE_K to 1.
- Updated Section 6.2 to indicate 0 or more MPL Seed Info rather than 1 or more.
- Updated Section 8 to define Realm-Local and moved to Protocol Overview section.
- Updated Section 10.1 to remove any implication that a device belongs to only one MPL Domain.
- Updated Section 11.2 to explicitly indicate state at the receiver.
- Updated Section 11.2 to explicitly specify that Trickle timer is reset in response to external events.

128:
- Updated Applicability Statement to indicate that (i) MPL may be used over LLN and non-LLN networks, (ii) scope is administratively defined, and (iii) hosts need not be aware of MPL but can be if they choose to.

129:
- Updated Section 4.2 to explicitly indicate that proactive and reactive are not mutually exclusive.  Proactive and reactive techniques may be used simultaneously within an MPL Domain.  For example, upon receiving a new MPL Data messages when both proactive and reactive forwarding techniques are enabled, an MPL Forwarder will proactively retransmit the MPL Data Message a limited number of times and schedule further transmissions upon receiving MPL Control Messages.

130:
- Updated Section 5.5 to clarify the meaning of DATA_MESSAGE_TIMER_EXPIRATIONS.

131:
- Updated Section 5.5 to clarify the choice of default parameter values in the document and specifically why setting IMIN=IMAX for data messages only is acceptable.

132:
- Updated Section 8 to define Realm-Local and moved to Protocol Overview section.
