Procedure for the Exchange of Attachments: Needs Work
Currently, the second item under "Procedure for the Exchange of Attachments" says this:
The Statement is sent using a Content-Type of multipart/mixed. Any Attachments are placed at the end of such transmissions.
For starters, the Statement is not sent; the request (or "transmission") is. So that should be improved.
It's possible that the second sentence--which lacks some technical specificity--could be removed entirely as a result of other nearby requirements. Namely:
The first part of the multipart document MUST contain the Statements themselves, with type application/json.
and
Each additional part contains the raw data for an Attachment and forms a logical part of the Statement. This capability will be available when issuing PUT or POST requests against the Statement Resource.
I think it's intended as a summary so I'd keep the second sentence.
Agree that the language could stand to be tightened up.
