// History:  Initially only rSolid and rMaterial elements worked.  Now,
// a Material or a Solid element inside the LogicalPart also works but
// this is handled outside this class.  Each Solid inherits from DDLSolid
// and in each Solid, the processElement method must call the setReference
// of the DDLSolid.  The Material element also works similarly.  Thus,
// by retrieving the rMaterial and the rSolid it actually will be handling
// Material and Solid subelements as well.
