Thomas,

I don't object about the name if we can find the best keyword.

I think it would be enough to mention in the corresponding
documentaiton that the user should take care of using the proper layer
type according to the output geometry type of the transformation.
We might also treat this in a separate RFC .however if we have the
geometry transformation framework implemented, it would not be a big
deal to hook it into the layers as well.

Best regards,
