SVG: titles and descriptions in one and only one language

These issues still occur in the final call draft.  Basically, the DTD allows only one title and description but allows it to be qualified by an xml:lang attribute.  It would simplify the DTD and
increase usability if multiple titles and descriptions were allowed and the user agent was allowed to select the description or title with the closest language to that of the user.  An acceptible
behavior would be to just select the first title or description.
