If attribute 'id' is missing all 'next' refer to next component in document. If 'next' is missing one label-less 'next' is assigned automatically. Presence of attribute 'entry' exposes this MCC through Loader class interface to external code. That is meant to be used in code which cretes chains dynamically like client utilities.

             This element is a Plexer. Optional attribute 'id' assigns identifier which is used to refer to this element from others. If not specified it will be assigned to "plexer" automatically. Sub-elements 'next' refer to next components in a chain and their content represent requested endpoints. In Plexer content of element 'next' represents Regular Expression pattern. For every incoming message path part of message's endpoint is matched pattern.In case of ordinary service element 'next' may look like
              <next>^/service$</next>
            If service is also responsible for whole subtree then simple solution is
              <next>^/service</next>
            But more safer solution would be to use 2 elements
              <next>^/service$</next>
              <next>^/service/</next>
            Unmatched part of message endpoint is propagated with incoming message in
            attribute PLEXER:EXTENSION and may be used by service to determine response.

Depending on produced result message may be either sent farther through chain or processing would be cancelled. Required attribute 'name' specifies name of plugin. Attibute 'id' creates identifier of SecHandler which may be used to refer to it. If attribute 'refid' is defined then configuration of SecHendler is provided by another element within ArcConfig with corresponding 'id'. Attribute 'event' defines to which queue inside MCC SecHandler to be attached. If it's missing SecHandler is attached to default queue if MCC has such. Names of queues are MCC specific. If not otherwise specified they are 'incoming' and 'outgoing' and are processed for incoming and outgoing messages. There is no default queue by default.
