66 * @short A helper class for attribute reference resolving.
68 * For easy resolving of attribute references, we have this class
69 * that can be used as a place holder for the real attribute use
70 * object it is referring to.
71 * So whenever the parser detects an attribute reference, it creates
72 * a XsdAttributeReference and returns it instead of the XsdAttributeUse.
73 * During a later phase, the resolver will look for all XsdAttributeReferences
74 * in the schema and will replace them with their referring XsdAttributeUse
77 * @ingroup Patternist_schema
