  • The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in RFC 2119.
  • All properties are classes, except for rel-sample, rel="enclosure" and rel-payment which use the rel-design-pattern.
  • Either album or fn (or both) are required.
