annotations on datatype definitin axioms fixed in OWL/XML
SimpleRenderer bug was hiding annotations from inspection
error in parsing annotated axioms where lists are involved

A datatype declaration axiom with an annotation and a faceted data
range would not be parsed correctly due to the order of the mop up 
actions - other handlers would steal some of the triples from the 
facet list before the annotated axiom handler got to them.

This bug did not exist in 3.5.0-SNAPSHOT. Might have resulted from
other bug fixes recently added to consume triples for annotations
with blank subject and literal annotation.
