Description

If one target "A" refers to another target "B" then the encounter order affects the validation because the code track all shapes processed.

If B is processed first as a target then A, B is executed twice - once as a top level target and once as part of A.

If A is processed first as a target then the parser shapes now includes B so processing B is skipped.

Note - the effect is only in the number of times constriants are executed , once or twice, not whether they are omitted.
