[undertow-dev] accessing msc services

[Tomaž Cerar]

so you probably mean, when some mgmt attribute / resource changes in your
subsystem how to pass that over to the handler.

Best way would be to have some msc service that holds the current data, and
you manipulate that service by :add/write-attribute handlers.
and your handlers have reference to that service, directly or indirectly is
different story.
