/**
 * This interface represents an Extension SIP header that was not defined at the
 * baseline of this specification. Extension Headers can be added as 
 * required by extending this interface assuming other endpoints understand the Header. 
 * Any Header that extends this class must define a "NAME" String constant identifying the name 
 * of the extension Header. A server must ignore Headers that it does not 
 * understand. A proxy must not remove or modify Headers that it does not 
 * understand. Implementation note : The implementation of any new headers 
 * added since version 1.1 of this specification
 * SHOULD implement ExtensionHeader for backwards compatibility (even if these
 * headers are defined in the current version of this specification).
 * Headers that are not part of the current version of this specification 
 * MUST implement ExtensionHeader.
