Most of the parameter entities in the DTD have a
"local.*" placeholder that is declared as empty in
the DTD.  It is meant to be overridden in a DTD customization
layer when you need to add elements to a parameter entity.
The trick is to include a "|" at the beginning of the
entity declaration so it merges smoothly with the rest of
the divcomponent.mix entity. For example:

<!ENTITY % local.divcomponent.mix "| mynewelement">
