	// If you want to send the same message to all transport protocols, include
	// the text of the message as a String value.
	//
	// If you want to send different messages for each transport protocol, set
	// the value of the MessageStructure parameter to json and use a JSON object
	// for the Message parameter. See the Examples section for the format of the
	// JSON object.
	//
	// Constraints: Messages must be UTF-8 encoded strings at most 256 KB in size
	// (262144 bytes, not 262144 characters).
	//
	// JSON-specific constraints:  Keys in the JSON object that correspond to supported
	// transport protocols must have simple JSON string values.  The values will
	// be parsed (unescaped) before they are used in outgoing messages. Outbound
	// notifications are JSON encoded (meaning that the characters will be reescaped
	// for sending). Values have a minimum length of 0 (the empty string, "", is
	// allowed). Values have a maximum length bounded by the overall message size
	// (so, including multiple protocols may limit message sizes). Non-string values
	// will cause the key to be ignored. Keys that do not correspond to supported
	// transport protocols are ignored. Duplicate keys are not allowed. Failure
	// to parse or validate any key or value in the message will cause the Publish
	// call to return an error (no partial delivery).

	//
	//  be a syntactically valid JSON object; and contain at least a top-level
	// JSON key of "default" with a value that is a string.   You can define other
