Consider renaming the beneficialOwnershipOrControl property

[kd-ods]

Summary of the bug or issue This property sits within the Interest object and could be better named to point to its function within BO data.

Additional context and details As this boolean property now functions (see the requirements around Representing beneficial ownership) a lot rests on this flag. It is the only element which identifies beneficial owners within a dataset. As such, we need to be really clear about what it means.

Suggested resolution

I think naming it something like 'meetsBeneficialOwnershipCriterion' would be helpful. It prompts the question 'what are the criteria?' which would need to be answered at the publication policy level. (And which would then involve pointing off to legal definitions etc.)
