Allow cross-use of MARC21 authority fields 500 and 510
Alma currently enforces strict validation rules that restrict the use of fields 500 and 510 based on the type of authorized heading (100 vs. 110), preventing cross-usage and triggering validation alerts.
However, in real cataloguing practice (including MARC21 examples and records from the National Library of Spain), it is both common and necessary to establish relationships between different types of authorities (personal ↔ corporate) using 5XX fields. For example, a 110 record may include 500 fields linking to persons, and a 100 record may include 510 fields linking to corporate bodies.
This restriction limits the accurate representation of relationships such as membership, authorship, or institutional affiliation, and hinders authority navigation.
Proposal:
• Allow cross-use of fields 500 and 510 between 100 and 110 authority records.
• Alternatively, provide a configurable option to relax this validation at the institutional level.

This rule can be overriden by deleting this parameter: Validation 1xx 4xx 5xx - same last 2 digits of Marc21 Auth validation on save
