Some notes concerning the version 2.0 of the tlp taxonomy:
- A new tag is introduced `TLP:AMBER+STRICT` to clarify the restriction to
share only with your organisation.
- A new tag is introduced called `TLP:CLEAR` which seems to replace
`TLP:WHITE` as it disappears from the version 2.0 of the official TLP
document.
- The old tag `TLP:WHITE` is preserved in the taxonomy. As we don't have
any official reference in the version 2.0 about the compatibility with
`TLP:CLEAR`, we *assume* it's a synomym from the original `TLP:WHITE`.
- The old tag `TLP:EX:CHR` is also preserved in the taxonomy for
backward compatibility.
We strongly recommend any users using the tlp taxonomy in their tools to review
workflows and ensure that the new version 2.0 is taken into consideration.

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.
