RFE #541444 observes that the content models for mediaobjectco and
mediaobject somehow drifted out of sync.

Today, mediaobject is defined as follows:

<!ELEMENT mediaobject %ho; (objectinfo?,
                           (%mediaobject.mix;)+,
			   caption?)>

Where mediaobject.mix is 

  videoobject|audioobject|imageobject|textobject %local.mediaobject.mix;

But mediaobjectco is defined as:

<!ELEMENT mediaobjectco %ho; (objectinfo?, imageobjectco,
			   (imageobjectco|textobject)*)>

I think it makes sense to restrict the content of mediaobjectco to imageobjectco,
but there's no reason not to allow caption.

Proposal: Change the content model of mediaobjectco to:

<!ELEMENT mediaobjectco %ho; (objectinfo?,
                              imageobjectco, (imageobjectco|textobject)*,
                              caption?)>

                                        Be seeing you,
                                          norm
