Regards for that.

I think its important that we move to an acceptance that *explicit* i.e. 
coordinate reference based georeferencing is preferable to *implicit* 
i.e. purely textual  as it removes a lot of ambiguity (and the need fro 
abstruse and tortuous ontological absurdities ;-) ). Ideally we should 
support both explicit and implicit in the same record i.e. use multiple 
DC:coverages, preferably leveraging the recommendations of GAP and 
reconciling DC and ISO worlds to best effect !
