SMIL 3.0 Metainformation

This specification defines the SMIL 3.0 Metainformation modules. Three extensions are defined in this specification: First, the SMIL 3.0 specification now allows metainformation to be placed on elements within the body instead of being restricted to the head element. This may make it easier to provide information on semantic intent within a SMIL presentation by making the binding of that information with the relevant nodes more local. Second, the text in this section makes it clear that several different types of metainformation encodings may be used within a single presentation. Third, the label attribute has been added to the Metainformation module so that extended content information can be provided for document components.
