FUNCTION

    UUIDv5 is meant for generating UUIDs from names that are drawn from,
    and unique within, some namespace.  They are created by computing an
    SHA1 hash of a Namespace UUID concatenated with the desired name
    value. The most significant 128 bits of this SHA1 value is then used
    to populate the UUID, sans the variant / version values of the field.
