Thanks for this good document! Please, find below a few minor comments.

[Section 2.2]

* The first paragraph has the only occurrence of "AIF object". I suppose that's what you call "list of pairs" in Section 2, right before Figure 1.
   
   If so, it may help to define "AIF object" there in Section 2, or to rather replace it with something like "list of (Toid, Tperm) pairs" here in Section 2.2.

* In the second paragraph, an access is possibly subject to conditions, not dictating them. Thus, shouldn't the right word be "conditionalized" rather than "conditionalizing" ?


[Section 3]

* s/e.g., 35 for Dynamic-DELETE/e.g., 35 would be the number for Dynamic-DELETE


[Sections 4, 5.1 and 5.2]

* In Section 4 and later on when registering the two media-types in Section 5.1, "local-uri" is used as default value for the Toid parameter.

   However, the new sub-registry defined in Section 5.2 (and where Toid values have to be taken from) is populated with an entry with value "local-part". Shouldn't they all indicate the same value?
   
   Also, perhaps it is better to name it "URI-local-part".

   
[Section 5.2]

* Suggested rephrasing:

   For both media-types application/aif+cbor and application/aif+json, IANA is requested to create a sub-registry within [IANA.media-type-sub-parameters] for the two media-type parameters Toid and Tperm, populated with:

   
[Section 6]

* The first bullet point has the only occurrence of "AIF information". Perhaps this is another name for what you called "AIF object" in Section 2.2? (see previous comment for similar considerations)

* The second bullet point says: "and that all parties understand Toid/Tperm pairs to signify the same operations."

   Suggested rephrasing: "and that all parties have the same understanding of each Toid/Tperm pair in terms of specified resources and operations on those"
