There are places where I am still waiting for some action to happen, and
these are marked by (***).  I have still to review this document and send a
chair review to the list.  I plan to do this after IETF 109.

In the meantime, please go through the draft shepherd writeup and let me
know if I have erred anywhere.

Shepherd writeup for draft-ietf-alto-unified-props-new-13

1. Summary.
The document shepherd is Vijay K. Gurbani, and the responsible area
director is
Martin Duke.

The document is a Standards Track document, targeted as a Proposed Standard.
The WG has chosen the requested publication type since this draft extends
base ALTO protocol in a normative manner.  Specifically, the document seeks
extend the base ALTO protocol (RFC 7285) by generalizing certain properties
attached to ALTO endpoints.

2. Review and consensus.
The document has a long history in the ALTO WG, having first made its
as an individual draft in March 2017, and was formally adopted as a WG item
April 2017 [1].  It is an important draft as two other WG drafts depend on
extensions defined in it.

A WGLC was issued for the draft in July 2020 [2].  Two reviewers were
that provided a detailed WGLC review [3,4].

The draft has broad consensus across the WG, no specific shortcomings have
identified with the current version of the draft.  Over the years that the
has been active in the WG, it has been subject to revisions based on the WG
expectations.  At least three implementations of unified-props are known.
first implementation was by one of the authors (Wendy Roome), corresponding
an older version of the draft.  A WG member (not a co-author) has
unified-props as well (details on the exact version implemented are not
And finally, a small group of WG members (including one co-author) are
to implement the latest version of the draft as part of an open GitHub

3. Intellectual property
The chair has received IPR declarations from Richard Yang, Sabine
Jensen Zhang, Wendy Roome.  (*** Kai Gao still remaining.)  During the
discussion of this I-D in the working group, no IPR issues has been raised
the best of my knowledge.

4. Other points
A formal review by the document shepherd is pending. (***)

IDNits reports 4 errors, 6 warnings, and 2 comments.  The errors and
must be fixed. (***)
