3. 5.6.2, second last sentence “tradeoffs” should be “trade-offs”

‌

Grammatical corrections:

1. 5.1.1. change “general purpose” to “general-purpose”

3. 5.3.1.1 (11) add a full stop after “seconds”
4. 5.3.1.1 NOTE 1 add a comma after “interoperability” so it reads “In order to facilitate interoperability, the authorization server…”

6. 5.3.1.2 numbered list: be consistent with the line ending punctuation (some times there is a comma, semicolon or full stop). Suggest adding a full stop and removing commas and semicolons.
7. 5.3.1.2 NOTE 2 add a full stop at the end of the note.
8. 5.3.2.1 NOTE 1 change “it's” to “its”: that is “… synchronise its own clock when…”

Regarding the quotes around .bank and .insurance: A different font is used to indicate that these are defined strings. I wouldn’t add quotes.

Regarding 5.3.1.1 (11): I fixed the use of the semicolon. A full stop is not correct here as the whole enumeration is one long sentence.
