Hi Juergen,

Next to Dan's editorial comments, I have some more.

There are actually two different audiences. See section 1.1 
http://tools.ietf.org/html/draft-trammell-ipfix-ie-doctors-02
NEW:

For giving guidelines to developers of new IPFIX information
elements, for helping the IPFIX experts appointed as IE-Doctors, and for better defining the process of registering new
information elements at IANA, the IPFIX WG will create an information
element developers guideline document.

"common ways", "specifying guidelines for the use of the IPFIX 
protocol": actually it's a real protocol specification, which will be 
standard track.
Should we be more specific?
Note that 
http://tools.ietf.org/html/draft-claise-ipfix-mediation-protocol-04 
title is: Specification of the Protocol for IPFIX Mediations

For example:

3. The export of IPFIX flow records from IPFIX mediators introduces a
set of potential issues at the protocol level, such as the loss of
information on the original exporter, loss of base time information,
loss of original options template information, etc. The IPFIX WG will
produce the protocol specifications in order to solve these IPFIX mediation
specific problems.

s/Flow/flow
