/**
 * This class holds the specification of a reference used to validate against.
 * The information structure is consistent with the 'references.xsd', so that
 * the elements of the 'references.xml' can be represented. A reference is
 * specified through its name and the characteristics: XSD:QName or a XSD:IDREF
 * reference and located as attribute or as sub element. There are possibly also
 * the allowed types of the referenced elements. The special field marks it for
 * additional hard coded handling. The number allows an easy look up in the
 * corresponding bachelor thesis.
