I'm rather asking than suggesting and just trying to understand the
problem. I only use a subset of the SRS-s that don't suffer from this
issue. I guess we're to expose something that's missing right now from
the SpatialReference API. That is possibly how the axes are
represented as XYZ coordinates. I was wondering if it would be enough
to expose one parameter to represent this like 'int
GetAxesDirection()' or 'SetAxesDirection(int)'. The reason is just to
keep it simple.
However it seems we would also want to represent a displayable name
for each axis following the WKT representation, so I've to retract the
statements above.
