to simplify part of that.. multi-row queries must have the same structure on 
each row (the same checked fields)

I've been going around in circles a bit due to lack of rules for handling 
self-joins and also multi-row queries.

Does the below make sense and seem reasonable without being too restrictive?

  * a table in a query:
  *   must have at least one row. Each row is TYPE_INSERT, TYPE_DELETE, 
  *   has zero or more rows of TYPE_NONE
  *   has zero or more rows of one only type other than TYPE_NONE
  *   containing TYPE_NONE and another type is a self-join
  * within a table:
  *   rows of same type must have join links in the same columns
  *   TYPE_DISPLAY rows must have checks in the same columns
  *   TYPE_INSERT and TYPE_UPDATE rows must use the same destination columns
