In section 17.4.11 it says:
"The content model of metadata is empty. Profiles that extend the SMIL
3.0 Language profile may define the RDF (Resource Description Framework)
schema to be used in extending the content model of the metadata
element. The Resource Description Framework is defined in the W3C RDF
Recommendation [RDFsyntax]. Other XML-based metadata formats may also be
included in a smiliar manner. Note that if any content is added to the
metadata element, a DOCTYPE must not be declared in the document."

Note the last sentence.
