Personally I do not like this way. We already discussed the idea of
separate option vs. filename encoding in regard to OGROpen() call and it
also applies here. Though it seems I have not succeeded in convincing
everyone that we should add open parameters to our open calls.

There is my thoughts on this topic:

 http://lists.osgeo.org/pipermail/gdal-dev/2007-November/014840.html

Note, that we already have format identification function in GDAL, so it
applies only for OGR. Open options addition should apply both for GDAL
and OGR.

Also I think it will be quite hard (or even impossible) to solve all HDF
issues without user control.

Best regards,
Andrey
