No, you didn't. You declared that it didn't matter.

Right. But the point is valid and hasn't been addressed in the spec.

It falls down for any use case. 

How do you expect applications to use a service when the only
description of the service is: "You can put a string here. The field is
named 'Title', which should give you a rough idea what this is about.
But we won't tell you if we translate it into morse code or signal it to
the user via smoke signs.". 

It just doesn't work. Your defense against this argument so far has been
that the examples are absurd and that there will be some implicit
understanding of what to expect - what kind of a 'spec' is that, if all
the semantics have to be read between the lines ?

Well, there was a call for the gnome side to 'sign off' on this spec a
few days ago. That's what I meant by reaching consensus.

I think what you have so far may be a workable basis for an API, but as
a specification it is not useful. Spec = API/Protocol + Semantics.
