<!--=================== The Switch Element ================================-->
<!-- In the head, a switch may contain only layout elements,
     in the body, only container elements. However, this
     constraint cannot be expressed in the DTD (?), so
     we allow both:
-->
<!ENTITY % switch-content "layout|(%container-content;)">
<!ELEMENT switch (%switch-content;)*>
<!ATTLIST switch
        %id-attr;
        %title-attr;
>

<!--=================== Media Object Elements =============================-->
<!-- SMIL only defines the structure. The real media data is
     referenced by the src attribute of the media objects.
-->

<!-- Furthermore, they have the following attributes as defined
     in the SMIL specification:
-->
<!ENTITY % mo-attributes "
        %id-attr;
        %desc-attr;
        region     IDREF           #IMPLIED
        alt        CDATA           #IMPLIED

        %fill-attribute;
        %sync-attributes;
        %system-attribute;
">

<!--
     Most info is in the attributes, media objects are empty or
     contain associated link elements:
-->
<!ENTITY % mo-content "(%assoc-link;)*">
<!ENTITY % clip-attrs "
        clip-begin      CDATA   #IMPLIED
