Further modified examples to track changes to XEP-0231.
The root element for media data is <media/>. This element MUST be qualified by the "urn:xmpp:tmp:media-element' namespace &NSNOTE;. The <media/> element MUST be contained within a <field/> element qualified by the 'jabber:x:data' namespace.
If the media is an image or video then the <media/> element SHOULD include 'height' and 'width' attributes specifying the recommended display size of the media in pixels.
-The <media/> element SHOULD contain at least one <uri/> element to specify the out-of-band location of the media data.
The <media/> element SHOULD contain at least one <uri/> element to specify the out-of-band location of the media data.
The 'type' attribute of the <uri/> element is REQUIRED. The value of the 'type' attribute MUST match the syntax specified in &rfc2045;. That is, the value MUST include a top-level media type, the "/" character, and a subtype; in addition, it MAY include one or more optional parameters (e.g., the "audio/ogg" MIME type in the example shown below includes a "codecs" parameter as specified in &rfc4281;). The "type/subtype" string SHOULD be registered in the &ianamedia;, but MAY be an unregistered or yet-to-be-registered value.
-The <media/> element MAY also contain one or more <data/> elements for distributing the media in-band. The <data/> element MUST be qualified by the 'urn:xmpp:tmp:data-element' as defined in &xep0231;. The encoded data SHOULD NOT be larger than 8 kilobytes.
