| <enum value="equivalent-to">The effective requirements of the source is equivalent in semantic meaning to the effective requirements of the target. The words may differ, but both mapped sets convey similar information with the same effective meaning. This relationship may be reversed, since `A equivalent-to B` also means that `B equivalent-to A`.</enum> | ||
| <enum value="equal-to">The actual requirements of the source are the same as the actual requirements target. Differences in capitalization, spelling, and grammar can be ignored, if these differences do not change the meaning. This relationship may be reversed, since `A equal-to B` also means that `B equal-to A`.</enum> | ||

| <enum value="intersects-with">The effective requirements of the source and target have some semantic equivalence, but not all effective requirements from each are contained within the other. This relationship may be reversed, since `A intersects-with B` also means that `B intersects-with A`. A lower granularity mapping, such as a statement level mapping using 'equivalent-to', 'subset-of', and/or 'superset-of', may provide a more functional mapping that allows for more inference than using this relationship type.</enum> | ||

| <p>When establishing relationships, mapping SHOULD be done at the control statement level where possible. This approach allows for more use of 'equivalent-to', which represents a stronger relationship than the other relationship types.</p> | ||
