Explain overlapping LDO keywords and protocol-specific metadata

[handrews]

• targetMediaType - the media type of the target that this LDO is designed to work with

• schema for HTTP Accept - all of the target media types you can request with HTTP

• submissionMediaType - the media type for constructing the submission request body using this LDO

• hint for HTTP Accept-Post - the possible media types you can use for the request in HTTP

There may be others that I'm not thinking of at the moment. There's no LDO keyword corresponding to Accept-Patch, though, so that's not one.
