I've been going around in circles a bit due to lack of rules for handling self-joins and also
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, TYPE_DISPLAY, TYPE_UPDATE
* 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
