def getElementDeclaration(self, attribute=None):
if attribute:<EOL><INDENT>return XMLSchemaComponent.getElementDeclaration(self, attribute)<EOL><DEDENT>return XMLSchemaComponent.getElementDeclaration(self, '<STR_LIT>')<EOL>
If attribute is None, "ref" is assumed, return the corresponding
        representation of the global element declaration (ElementDeclaration),
        To maintain backwards compat, if attribute is provided call base class method.
