(proposal) on metadata in documents

[Björn Wärmedal]

I've seen some people put key/value type metadata in their gmi files
already ("tags: this,that,whatevs" for example). Go ahead and do it if
you want; I personally like that you want to put them at the end of
the document, where they won't bother anybody.

As for including it in the spec... I'd rather not. Treat them as
optional extensions :)
