-// This file contains utilities related to working with "facets".
-//
-// A "facet" is defined as the manifestation of a logical application on a given
-// platform. For example, "My Bank" may have released an Android application
-// and a Web application accessible from a browser. These are all facets of the
-// "My Bank" logical application.
-//
-// Facets that belong to the same logical application are said to be affiliated
-// with each other. Conceptually, "affiliations" can be seen as an equivalence
-// relation defined over the set of all facets. Each equivalence class contains
-// facets that belong to the same logical application, and therefore should be
-// treated as synonymous for certain purposes, e.g., sharing credentials.
-//
-// A valid facet identifier will be a URI of the form:
-//
-//   * https://<host>[:<port>]
-//
-//      For web sites. Only HTTPS sites are supported. The syntax corresponds to
-//      that of 'serialized-origin' in RFC 6454. That is, in canonical form, the
-//      URI must not contain components other than the scheme (required, must be
-//      "https"), host (required), and port (optional); with canonicalization
-//      performed the same way as it normally would be for standard URLs.
-//
-//   * android://<certificate_hash>@<package_name>
-//
-//      For Android applications. In canonical form, the URI must not contain
-//      components other than the scheme (must be "android"), username, and host
-//      (all required). The host part must be a valid Android package name, with
-//      no escaping, so it must be composed of characters [a-zA-Z0-9_.].
-//
-//      The username part must be the hash of the certificate used to sign the
-//      APK, base64-encoded using padding and the "URL and filename safe" base64
-//      alphabet, with no further escaping. This is normally calculated as:
-//
-//        echo -n -e "$PEM_KEY" |
-//          openssl x509 -outform DER |
-//          openssl sha -sha512 -binary | base64 | tr '+/' '-_'
-//

-// and obviously, it does not recognize the "android" scheme. Therefore, after
