This issue references the Plant Environment Ontology, which is registered in Identifiers.org at https://registry.identifiers.org/registry/eo Actual: `^(P)?EO\:\d{7}$` Expected: `^EO:\d{7}$` Issues: - the optional `P` does not work - there's a redundant escape for the colon - EO isn't the same as the prefix, so how does namespaceEmbeddedinLUI help a user generate a valid CURIE?
