# Adds causal consistency document to the selector, if one can be
# constructed.
#
# This method overrides the causal consistency addition logic of
# SessionsSupported and is meant to be used with operations classified
# as "read operations accepting a read concern", as these are defined
# in the causal consistency spec.
#
# In order for the override to work correctly the
# CausalConsistencySupported module must be included after
# SessionsSupported module in target classes.
