# The context within which a query is performed against a Container.
#
# The context within which a query is performed against a Container
# is complex enough to warrent an encapsulating class. This context
# includes a namespace mapping, variable bindings, and flags that
# determine how the query result set should be determined and returned
# to the caller.
#
# The XPath syntax permits expressions to refer to namespace prefixes, but
# not to define them. The Context class provides a number of namespace
# management methods so that the caller may manage the namespace prefix
# to URI mapping.
#
# The XPath syntax also permits expressions to refer to variables, but not
# to define them. The Context class provides a number of methods so
# that the caller may manage the variable to value bindings.
