The value of tmnxBsxAppFilterProtocol specifies
the particular protocol signature to match against
to resolve to tmnxBsxAppFilterApplication. If set
to an empty string, no match on protocol is done.
If an attempt is made to set this object to a string
that does not match a tmnxBsxProtName value from the
tmnxBsxProtTable, an 'inconsistentValue' error is
returned.
