Hi Martin

but is there a strong reason to deviate from
it?

Only a week reason ( clone() method ). But I think you are right and it might be better to follow the ISO model to be more compatible with other libs.

Regards,
Marco

Thanks - I thought this was already asked, but couldn't find where...

IMO the hierarchy in QGIS should follow the one in ISO and OGC models.
Maybe right now there is no practical advantage for the implementation
to follow the hierarchy, but is there a strong reason to deviate from
it? It seems confusing that multi-polygon cannot be cast to
multi-surface. I am afraid that things like this can bite us later...

Martin
