+illustrates a quick and dirty way to persist an XML document expressed using
+ElementTree and pickle.
 
 This is a trivial example using PickleType to marshal/unmarshal the ElementTree
-document into a binary column.  Compare to explicit.py which stores the individual components of the ElementTree
-structure in distinct rows using two additional mapped entities.  Note that the usage of both
-styles of persistence are identical, as is the structure of the main Document class.
