                    The destroy attribute of FilterConnection will be set to true when
                    the client decides
                    to destroy a persisted filter before all of its
                    applicable messages have been pulled. If and when the
                    client does
                    pull all of the persisted filter's applicable messages, then the web
                    service will
                    automatically destroy the connection and return an empty
                    pull response. If the client does not pull
                    all of a persisted filter's
                    applicable messages and does not explicitly destroy the persisted filter
                    by setting the destroy attribute to true, then based on an agreed upon
                    out-of-band policy, the web
                    service will expire the persisted filter
                    after X number of days.
