Hello,
The new registry says:
  System Ports are assigned by IETF
  process for standards-track protocols, as per [RFC1340].  User Ports
  are assigned by IANA using the "Expert Review" process, as per
  [RFC5226].  Dynamic Ports are not assigned.
I don't understand referencing RFC 1340 here.  You could better change 
this to "System Ports are assigned per "Standards Action" or "IESG 
Approval" process, as per [RFC5226]".  IESG Approval is assumed by the 
RFC-to-be, Section 8.1:
    o  Reserved numbers and names are generally only assigned by a
       Standards Action or an IESG Approval,
Also, the new registry doesn't seem to match the following rule:
    The new assignment procedure
    conserves resources by assigning a port number to an application for
    only those transport protocols (TCP, UDP, SCTP and/or DCCP) it
    actually uses.  The port number will be marked as Reserved - instead
    of Assigned - in the port number registries of the other transport
    protocols.
Such entries as:
tcpmux               1         tcp    TCP Port Service Multiplexer 
[Mark_Lottor]                       [Mark_Lottor]
tcpmux               1         udp    TCP Port Service Multiplexer 
[Mark_Lottor]                       [Mark_Lottor]
should be:
tcpmux               1         tcp    TCP Port Service Multiplexer 
[Mark_Lottor]                       [Mark_Lottor]
tcpmux               1         udp    TCP Port Service Multiplexer 
[Mark_Lottor]                       [Mark_Lottor]
                      1        sctp    Reserved
                      1        dccp    Reserved
etc.

Attention:  We recently combined and converted the Service Names and 
Port Numbers registry in accordance with a recently approved document 
to become an RFC.  The legacy registries will be maintained for 2 more 
weeks so that anyone running scripts or gathering information can 
adjust/update what they need to.
Legacy URLs:
http://www.iana.org/assignments/service-names/service-names.xml
http://www.iana.org/assignments/port-numbers
NEW URL:
http://www.iana.org/assignments/service-names-port-numbers/service-names-port-numbers.xml
We are aware that the new registry is very slow to load in some 
browsers and we are working on resolving the speed issue.
If you have any questions, please do not hesitate to contact me.
Thank you,
Michelle Cotton
