    Initiates validation of domain control. The AHP calls this after
    placing

    the ACME challenge token at the specified location (DNS or HTTP).

    The RA validates domain control, which is required before issuing both

    server and identity certificates. A single domain validation is used

    for both certificates.

    The RA will automatically determine which validation method to use
    based

    on the registration configuration and what is discoverable.

    Verifies that all required DNS records have been configured correctly.

    The RA knows which records are required based on the registration

    and will check for all four required records (HTTPS, TLSA, \_ans,
    \_ra-badge).

    This is the final step for external domain registration.
