[gdal-dev] WCS driver

[Peter Baumann]

FWIW, OWS Common 2.0 is known to be flawed in several aspects (we spec writers
suffered dearly - from the resources it needed to discover, to finding
workarounds in the spec, to explaining to people...). Trust me, the namespace
issue is just a minor one in comparison... OGC is looking to get something
revised since 2 (?) years now, and until that will come we will have to live
with this situation, unfortunately and sometimes painfully.

just 2 cents,
Peter
