Somewhat tardy responses to  your comments:

Point taken, will do this in the next revision.

We thought that it might be necessary in some circumstances for the MGC to
be able to write values to the MG for Current Pulse Count and Pulse Count
Since Last Report.  That's why we chose to use Properties and not Statistics
for these.  In retrospect, this requirement does not seem to be valid and I
agree that it would be more natural to treat these as Statistics.  Will
change this in the next revision.

This is not necessary since the MGC knows the value it set for the Report
Period (parameter rp of the Periodic Report event pr).  Hence when it
receives a Periodic Report event, it knows that this number of pulses must
have been applied by the MG since the last Periodic Report event (or since
metering was enabled by the em signal, if this is the first Periodic Report
event).

Internet-Drafts are also available by anonymous FTP. Login with the
username
"anonymous" and a password of your e-mail address. After logging in,
type "cd internet-drafts" and then
	"get draft-taylor-megaco-enhalpkgs-00.txt".

A list of Internet-Drafts directories can be found in
http://www.ietf.org/shadow.html 
or ftp://ftp.ietf.org/ietf/1shadow-sites.txt

Internet-Drafts can also be obtained by e-mail.

NOTE:	The mail server at ietf.org can return the document in
	MIME-encoded form by using the "mpack" utility.  To use this
	feature, insert the command "ENCODING mime" before the "FILE"
	command.  To decode the response(s), you will need "munpack" or
	a MIME-compliant mail reader.  Different MIME-compliant mail readers
	exhibit different behavior, especially when dealing with
	"multipart" MIME messages (i.e. documents which have been split
	up into multiple messages), so check your local documentation on
	how to manipulate these messages.

Below is the data which will enable a MIME compliant mail reader
implementation to automatically retrieve the ASCII version of the
Internet-Draft.
