I've a question about the usage of vacabularies in an ensemble. Given a vocabulary V which is used in an ensemble and two vocabularies V1 and V2, which are used by different backends of the ensemble (e.g. omikuji and mllm). V1 and V2 are subsets of V, with different subsets of the concepts and a different set of labels (gold standard (TSV) and TTL). The concept URI are stable in all versions of V.

1. Is it possible to use such an setup in order to tweak the backends used in the ensemble?
2. Does the the vocabulary V acts as an allow-list? Are the suggestions of the backends (e.g omikuji, mllm) tested against the vocabulary V?

Background: We want to aggressively tweak the vocabulary (reduce concepts and manipulate labels) for the mllm backend, to improve the results.
