An Endpoint Address is composed of four components: a protocol (also called a scheme), a protocol address (also called an authority), an optional service name and optional service parameter.

The Protocol

• Describes the method of addressing used by the remainder of the endpoint address.
• Indicates how the address will be resolved, ie. who will resolve it.
• Cooresponds to the "scheme" portion of a URI in W3C palance.
• May not contain the ":" character.

The Protocol Address

• Describes the destination entity of this address.
• Form is dependant upon the protocol being used.
• Cooresponds to the "Authority" portion of a URI in W3C palance.
• May not contain the "/" character.

The Service Name (optional)

• Describes the service that is the destination. A service cannot be a protocol address because a service must have a location; a group or a specific peer.
• Form is dependant upon service intent. This is matched as a UTF-8 string.
• May not contain the "/" character.

The Service Parameter (optional)

• Describes parameters for the service.
• Form is dependant upon service intent. This is matched as a UTF-8 string (if it is used for matching).
