Which error ? The output of the above commands looks right. There is no error as
far as I can see...

Yes, that's expected.

Cool

AFAICS, OGR did open the file. It is just that without the -al option, or
specifying the layer name (elements), the features won't be listed in the
console. I don't see any issue in the above, but I've perhaps not understood
what you mean.
