In table (4), three types of contexts are subsumed:
• direct contexts, addressed by absolute or unbounded position instantiation, with the
target word form as position 0.
• relative contexts, addressed by the LINK feature and related to another, preceding,
context functioning as new position 0.
• BARRIER contexts which are always negative, with their scope defined by the
instantiation of the unbounded context they refer to.
Most rules, with the exception of some default mapping rules, have at least one direct
context, and 75% of the 2739 "global" rules (with at least one unbounded context
condition) have LINK or BARRIER contexts, or both. Thus, 2085 rules feature at least
one LINK context, and 2017 rules have at least one BARRIER context.
