XmNcreateCallback is a "fake" callback resource used only in UIL files.  The
problem is that when you specify a widget tree in a UIL file you have no way
of mapping actual widgets to resource IDs.  So when you retrieve a widget
tree using one of the MrmFetch functions, the XmNcreateCallback for each
widget will be called, and this is where you can do your widget-to-ID mapping.
Just treat it like any other UIL callback, but remember that it doesn't
really exist -- you can't try setting it when creating widgets dynamically.

This should probably be documented somewhere.
