<channel>

The schema defines this element differently in each context it is declared in.

In <type:RemoteContentPropType>: Information about a specific content channel.
In <header>: A transmission channel used by the message

Declared locally only; it is not a valid document root.

Note

Usage note

User Note: A channel identifier is used to provide recipients with information for selecting, routing, or handling otherwise the content of the message. The channels represent streams in a multiplex: a message may be sent on different channels – e.g. one for text, one for pictures – and each reception point will be able to filter on channel values. The structure of this string is not specified by the IPTC.

For rules on concept identifiers, see Use of Concept Identifiers
