# The Context class encapsulates the context within which a query
# is performed against an Container. The context includes namespace
# mappings, variable bindings, and flags that indicate how the query result
# set should be determined and returned to the caller. Multiple queries can
# be executed within the same Context;
#
# Context allows you to define whether queries executed within the
# context are to be evaluated lazily or eagerly, and whether the query
# is to return live or dead values.
#
# The Query syntax permits expressions to refer to namespace prefixes,
# but not to define them. The Context class provides namespace
# management methods so that the caller may manage the namespace prefix to
# URI mapping. By default the prefix "dbxml" is defined to be
# "http://www.sleepycat.com/2002/dbxml".
#
# The Query syntax also permits expressions to refer to externally
# defined variables. The XmlQueryContext class provides methods that
# allow the caller to manage the externally-declared variable to value
# bindings.
class BDB::XML::Context
# Get the value bound to a variable
#
def [](variable)

# Bind a value to a variable
