Comment:

 this is an artifact of the OpenLayers library.  The DWF and AJAX viewers
 don't use OpenLayers as the mapping engine.

 In theory you can do this by simply not specifying a maxExtent for the
 layer (or map) but you then end up with the default maxExtent of
 -180,-90,180,90 and maps in EPSG:4326 can zoom out to that, but it is
 definitely wrong for maps in other projections.

 IMHO there are problems with the way that the map extent handling has been
 implemented in OpenLayers, and I suspect mostly due to OL origins as a map
 tiling client, but that is the behaviour that OpenLayers provides.

 If you can provide an example of OpenLayers that allows zooming out beyond
 the maxExtent, please re-open this ticket with a link.
