Information.
Qualification.
For a claim to qualify, there must be some sense to the claim, like a popular, governmental, personal, hierarchical or indirect (mostly implied) claim, these we shall will break down simply:
If there is both, for example, a popular and governmental claim from the same nation, they should be listed separately. In the case of a popular claim, the endorser of the claim can (though in a case like the Eastern Roman Empire, where its popular claim lasted over many rulers, should simply not be listed) be listed instead of a claimant, this can be marked with (E), this can also be used in special cases like the concept of Russia being Third Rome.
