RETENTIVE TAGS (BOZZA)
------------------------------------------------------------------------------

[Shared] [tags] can be set retentive, so they will
keep their values between [JSup application] run
sessions. This behaviour could be useful for [JSup
application] level parameters. Persistence data is
stored in the SHARED.jpers file in the [Historical]
data dir (see [JSup Application properties]), so
the [Historical] data dir must be set and must
exist for tag retentiveness to work.
