Hi,
Well, I was thinking simply X and Y for giving the point to be queried because
I thought that BBOX can't be a point. But I have mostly used WCS 1.0.0. Is it
so that in WCS 2.0 core the "slicePoint" can be used for this? And standard
range subsetting can be used for selecting what is queried, like list of bands
from multiband satellite images?

Hello,
for my use case, the standard WCS 2.0 options were sufficient, only the
outputformat is not described by a standard, but that's not so relevant as it's
plain text json.
If you are thinking about more complex queries, than you can have a look at
http://www.opengeospatial.org/standards/wcps . (Do note that writing a full
implementation would be very complex, and also the queries which you have to
send as a client can become quite
large.)<http://www.opengeospatial.org/standards/wcps>
What type of vendor options were you thinking
about?<http://www.opengeospatial.org/standards/wcps>
