This is my first set of improvements I see that need to be reviewed in the protocol's documentation. I'll try to add more along the way. Thanks.

Json Page

http://project-haystack.org/doc/Json

• Misspelling in Type Mapping section: DateTime has requrired timezone name

Trio Page

http://project-haystack.org/doc/Trio

• Wording in Overview: It the primary format for authoring the tag definitions on the Project Haystack site itself. Should be "It is the".
• Misspelling in Simple Example Summary: This is a string value which spans multiple lines with one or more space characgter

Operations Page

http://project-haystack.org/doc/Ops

• Wording in Overview section: "Each operation is specifies the format and options of the request grid and response grid." Should remove "is".
• Misspelling in Formats section: "The formats op is used to query which MIME types are availble to read and write grids."
• Wording in Formats section: "send: Marker tag is server can write this format in responses (client can request response in this format)". Should be "if" instead of "is" similar to description in receive property.
• Wording in InvokeAction section: "The invokeAction op is used to invoke an user action on a target record.". Should be "a user".
• Wording in WatchSub section: "Request: a row for each entity to subscribe to with the an id column and Ref values. Should remove "the" or "an".
• Wording in WatchSub section: "watchDis: Str debug string required when creating a new watch". Should "debug" be "display"?
• Wording in WatchUnSub section: "close: Marker tag to close the entire watch The request also ." Appears the sentence is not completed, but not sure what it should state.

Thanks for taking the time to post those errors Greg. I pushed a fix for next website release
