- Chapter 22 in ETL gives a fairly detailed description of the algorithm
- for system-level validity checking. It does not describe an incremental
- version of this algorithm, but this just involves caching the right
- information for re-use.

- I'm not quite sure how a presentation of the algorithm can be reasonably
- described as "being evasive on the subject", but that's a judgement call
- I suppose (:-).
