+ * Important concepts to keep in mind:
+ * 1. Keys are unique; there can never be 2 tags with the same key. This is
+ * also meant semantically, i.e., a demuxer should not knowingly produce
+ * several keys that are literally different but semantically identical.
+ * E.g., key=Author5, key=Author6. In this example, all authors must be
+ * placed in the same tag.
+ * 2. Metadata is flat, not hierarchical; there are no subtags. If you
+ * want to store, e.g., the email address of the child of producer Alice
+ * and actor Bob, that could have key=alice_and_bobs_childs_email_address.
+ * 3. A tag whose value is localized for a particular language is appended
+ * with a dash character ('-') and the ISO 639 3-letter language code.
+ * For example: Author-ger=Michael, Author-eng=Mike
+ * The original/default language is in the unqualified "Author" tag.
+ * A demuxer should set a default if it sets any translated tag.
