I have received very few comments on Wednesday evening's draft. MegacoHGCP9.pdf is available at: ftp://standards.nortelnetworks.com/megaco/docs/Oslo99/MegacoHGCP9.pdf It has the following changes:

1. Abdallah Rayhan and his colleagues at Nortel Networks

have been furiously putting together a real parser while I'm merrily changing the syntax. They have provided some updates that make the grammar consistent, error free and presumably more regular. While the changes do in fact modify the syntax, they should not introduce any semantic changes except as noted.

A summary of changes are: some spelling errors were corrected several places where I had made commas optional were put back to requiring commas several places where parameters should have been optional were fixed so that they were optional several ABNF rule construction errors were fixed a change was made in eventParameter to fix a syntax ambiguity an error where SignalsDescriptor had a RequestID was fixed an option to return an error from Transaction was added

2. Time Notation is changed per Chris Ross' suggestion

3. Nancy Greene from Nortel Networks has updated the examples

They are believed to be reasonably consistent with the current grammar.

4. I have clarified wording to expressly state that a Termination can

only exist in one Context at a time.

5. I have clarified wording in termination Mode to state that

send/receive is with respect to the Termination. A Termination in Send mode can only talk, it cannot listen.

6. Text on the local, tx and rx descriptor was replaced/reworded, and

Mode text was restored/relocated to the Local descriptor section.

A new Internet Draft referencing this pdf has been submitted, and will be announced in a few days.

For those attending the SG16 Berlin meeting, there will be a hard copy of this draft, with change bars from APC-1610 available. A zipped version of the pdf and doc files is also on the ftp site for your use. Please note that files with "itu" in the file name have the ITU headers and some extra text not in the IETF version (the macros were invoked to show ITU text).

I thank all of the people who have contributed to this editing process. Other than the missing text on defining packages that should be available very soon, and the separate document with the default packages, I feel that the document is getting very close to last call quality.

Any further review you would care to do would be most welcome. Feature requests will probably be discouraged.
