 \subsection{Discussion}
-Some values in the catalog need special treatment. So we will have a central property for the catalog, and a number of special properties. An entry like Lang can be added to the catalog property, but e.g ViewerPreferences needs a special property, and the general prop should only contain the indirect reference to the dict obj. Probably a number of tests are needed to prevent users to write into the wrong prop.

An entry like Lang can be added to the catalog property, but e.g ViewerPreferences needs a special property, and the general prop should only contain the indirect reference to the dict obj. Probably a number of tests are needed to prevent users to write into the wrong prop. Check when the catalog is written and when the last changes can be added. Is e.g. end document to late for beamer?
