Nit-pick: HTTP query param

[DerGuteMoritz]

Just a minor nit I noticed while studying README.md. It speaks of an "HTTP query param" here:

A use of transit might be a stream or file containing a series of elements, but it could be as small as the conveyance of a single element in e.g. an HTTP query param.

I think It would be more correct to say "URI query param" instead. Of course, "HTTP query param" can be understood as a common colloquialism but thought I'd mention it since in the context of a technical spec you might want to be more precise.
