Exclusive property allows to express if a predicate or a value is exclusive.
The exclusive property applies at namespace level (if the predicate is exclusive) or
at predicate level is the value is exclusive.
TLP and fr-classif updated with exclusive property.
The exclusive property can be used by the software (e.g. MISP) to warn users
if (s)he tries to add multiple tags on the same element (attribute, event...).
It's up to the configuration of the software to enforce it or not.
By default, tags are not exclusive.
