I dont see that it should be impossible to support a converter in the binding - generally speaking we ought to be able have a mechanism that allows us to drop in capabilities to handle any native data type we encounter for a complexAttribute. Rather than a function that converts a specific JTS object to a particular data type, perhaps we could have accessor functions in CQL and map them.
Inverse functions are a priority - I'm hoping one day to get back into this to make geomteryless work - my life has been rather taken over by other projects and research around conceptual modelling, but there is light at the end of the tunnel to get back to implementations.
