# Modify encapsulates the context within which a set of documents specified by
# a query can be modified in place. 
# 
# The modification is performed using the methods 
# BDB::XML::Container#modify and BDB::XML::Document#modify

# There are two parts to the object -- the query and the operation. 
# The query identifies target nodes against which the operation is run. 
# The operation specifies what modifications to perform.
