2.2.3.2 Content-Type

When the Content-Type header is included in an ANNOUNCE request that is sent to a client in accordance with [DLNA] guideline 7.4.261, then the Content-Type header is defined as follows.

  
 Content-Type = "Content-Type: application/x-wms-extension-cmd"

If the Content-Type header is used in other RTSP requests and responses, or in an ANNOUNCE request for which [DLNA] guideline 7.4.261 does not apply, then the Content-Type header follows the syntax defined in section 12.16 of [RFC2326].
