I've spent a bit more time revising the 0002 patch so that we're a bit more strict about when we mark a partition as interleaved. For example, if the DEFAULT partition happens to be the only partition, then I'm no longer classing that as interleaved as there's nothing for it to be interleaved with. This also fixes up the not-so-robust check that I had to check if the NULL partition allowed other Datums. David
