Hi,

The media description describes the properties, associated with a data flow, that an endpoint provides in order to properly be able to process data associated with the data flow. It includes IP address and port, and properties specific to the transport protocol and media type associated with the data flow.

...or something like that.

I don't think we need to make it more complicated.

Regards,

Christer

    This came up because Ben felt that the current definition was inadequate 
    because it is only syntactic. He asked for a semantic definition to be 
    added.
    
    IMO the fact that it seems hard to come up with a suitable semantic 
    definition makes it more important to do so.
    
    	Thanks,
    	Paul
