/**
 * The two label schemes the admin page offers to start from (enterprise
 * pack item 3). Markings follow RFC 7444 (SIO-Label), Sensitivity values
 * RFC 2156 (what Outlook shows).
 *
 * The German public-sector preset stops at VS-NfD on purpose: higher grades
 * (VS-VERTRAULICH and up) need IT approved for them (VSA § 50 Abs. 4) and
 * must not be offered in a mail client that isn't. Even VS-NfD needs
 * approved IT and BSI-approved encryption outside an approved network
 * (§ 50, § 55); the label only marks the message.
