Playlist Attributes

The following attributes are supported for server-side playlists. An attribute is a name/value pair that provides information about the element with which it is associated.

• Note   The typographic conventions used to represent the syntax of each attribute are those used in the SMIL 2.0 documentation rather than those used in the other reference sections of this documentation. In particular:
  • Optional items are identified by a question mark (?) at the end.
  • Parentheses are used to group grammar elements of the attribute.
  • Items that must be typed exactly as shown are in quotation marks.
  • The vertical bar character (|) means a logical OR.
