Cool I think you have found the heart of the problem :-)
We would like the encoder to pull out two values the geometry and the crs.
Any way we can modify it to ignore GeometryAttribute and provide our own
binding for GeometryAttribute?
Or pull out two values (the geometry and crs)?
If you have to as an quick hack you could stuff the crs into the geometry at
this stage (but that is a little sad as the library would then be using
Geometry user data for our own internal needs; and wrecking the value as passed
into the encoder).
