* Structure

The file contains a JSON object, whose members are MIME types and
their properties, represented as nested JSON objects.

* Properties

application [string?]

  The alternative MIME type in the |application/*| type, if any.

  Whether it is a BER (Basic Encoding Rules) type or not.  This flag
  is not set for MIME types with the |+ber| structured syntax suffix.

blacklisted [boolean]

  Whether it is in the implementation-neutral part of the type
  blacklist or not
  <http://www.whatwg.org/specs/web-apps/current-work/#type-blacklist>.

clipboard [boolean]

  If true, the MIME type is sometimes used in Web clipboard
  processing.

composite [boolean]

  Whether it is a composite type or not.

  Whether compression is appropriate for the type or not.  If |1|, it
  seems appropriate.  If |0|, in appropriate.  Otherwise, unknown.

  <https://fetch.spec.whatwg.org/#corb-protected-mime-type> or not.
  If |1|, it is a CORB-protected MIME type unless otherwise specified.
  If |false|, it is NOT a CORB-protected MIME type.  If |depends|, it
  is NOT a CORB-protected MIME type but the CORB check steps can

    |type_only|         The (non-conforming) type value, used alone with
                        no following subtype.  Some of values of this type
                        come from RFC 1049.
    |type_only_pattern| Same as |type_only| but represents a set of types
                        rather than a single type, using |*| as wildcard.

    |MAY|    The XPointer scheme may be supported.

  There are two special namespace values.  The empty string represents
  the null namespace.  If the namespace is |#| and the local name is
  |other|, the value is applied to any XPointer scheme not explicitly
