The Content-Type header is used as specified in [RFC2616]. However, because this document describes messages for the application/atom+xml (section, application/json (section, application/json;odata=verbose (section, application/xml, text/plain, and text/xml formats, a data service client or server SHOULD only use HTTP messages with a Content-Type header value as shown in the ABNF grammar that follows and is specified in [RFC5234]. The exception to the above rule is when messages are used that represent a Media Resource [RFC5023] or the raw value of an entity's property (see section

 Content-Type     = "Content-Type:"
                    / "application/atom+xml;type=entry"
                    / "application/atom+xml;type=feed"
                    / "application/json;odata=verbose"
                    / "application/json"
                    / "application/xml"
                    / "text/plain"
                    / "text/xml"
                    / "octet/stream")
                    ";" <Remainder of rule is per the Content-Type rule in [RFC2616]>
