Re: [Ietf-message-headers] Registration request for EntityId, Isolation, OData-MaxVersion, and OData-Version

[Ted Hardie <[e-mail]>]

Hi Chet,

I'm a little confused on one point.  The Isolation header states that it
was called OData-Isolation in version 4.0, but the linked ABNF document
says:

isolation  = [ "OData-" ] "Isolation" ":" OWS "snapshot"

That seems to indicate that both ODate-Isolation and Isolation are expected
to be valid for this token.  The ABNF for EntityID is similar:

entityid   = [ "OData-" ] "EntityID" ":" OWS IRI-in-header


Can you clarify the intent here?  Are both expressions of this token
expected to continue?

In general, "Isolation" seems to be a very general concept, and the
reservation of it, unadorned, for a single token use ("snapshot") is
somewhat surprising compared to the more-obviously scoped OData-isolation.
EntityID seems similar board in possible usage outside the OData
specification.

regards,

Ted Hardie
