'references' not handled in new AbstractDataPackage class
'references' are not handled in AbstractDataPackage class!
Maybe this can be handled by examining the context node in the various xpath
searches. If context node has a 'refernces' child, then follow reference to the
subtree with the referenced id and use it as the context (if it is not also a
'references' is an eml2 concept. maybe it should be handled in eml200 class
rather than in abstractDataPackage.

added a method called 'getReferencedNode' which checks for 'references' and
finds the referenced node in the dom. Used for resolving references in entity
and attribute arrays in the AbstractDataPackage class. [Method is actually
implemented in the EML200DataPackage class, since it is eml2 specific.]
