change altz to z in :coordinates attribute

[RussellSenior]

coordinates attribute refers to an undefined variable altz, which doesn't exist as a variable or anything else, afaict, but z does.

Thanks @RussellSenior 😄

I'd love to merge this fix, but we're going to have to hold off until we've finalised v1.6. (Then we can start applying the agreed changes for 1.7 and any other fixes.)

Hi @RussellSenior. This repo has now been officially adopted and moved to the cf-convention organisation. But the official process for changes to the conventions still requires going through the CF trac system. Once the change has been agreed there it can be applied via a PR here. Sorry if that seems a long-winded way of doing things but the CF community don't seem to be ready to switch to GitHub yet.

Would you be happy to create a ticket in the trac system for this change?

[JonathanGregory]

Yes, this change needs a trac defect ticket. It looks like a mistake and fixing it would not be a change to the intention of the convention, but the point of a defect ticket is to give a chance for anyone to disagree with that. Defect tickets are agreed by default if no-one objects within three weeks. See http://cfconventions.org/errors.html. Thanks for noticing it. Jonathan

Now that we have hashed out github governance, this should just be merged as far as I'm concerned. Anyone disagree?
