type_ The criteria to match the context's type.
type_regex If true, regular expression matching
will be used on the type.
range_ The criteria to match the context's range.
range_subset If true, the criteria will match if it is a subset
of the context's range.
range_overlap If true, the criteria will match if it overlaps
any of the context's range.
range_superset If true, the criteria will match if it is a superset
