COMMENT:
----------------------------------------------------------------------

I know very little about this, but just checking:
- I trust that a network that mixes routers that use application attributes,
and not, will not lead to long-term routing loops in spite of them not having a
common picture of the network?

- It is odd that a link that advertises a zero-length flags field means support
for RSVP-TE is “ambiguous” (sec 5). What are the implications of this? When is
it OK to use a zero-length flags field given this ambiguity? In a standard, can
we not decide on a meaning to eliminate the uncertainty? I would appreciate
some language here to answer at least the first two questions.

- as the TSVart review points out, the length field wastes 3 bits of 7 because
the maximum length is 8. You could reserve them or even use them to encode
these three legacy applications.

Nits:

Abstract:
In “these link attributes for a given attribute” add a comma after both
instances of attribute(s)

Sec 4 2)Application. Add a space

Sec 5. Missing a period at the end of “existence of link attribute
advertisements”
