If that is the case, our spec is inconsistent. We have a section that states:

"Note that a general URI fragment or query string specified on a media
resource may contain several field-value pairs. They are not
restricted to the ones specified here, since applications may want to
use additional other parameters to communicate further requests to
custom servers."

The idea behind this was to allow applications to add further
name-value pairs which will be executed on top of the ones we already
have defined.

I was always under the impression that we had agreed that additional
name-value pairs are allowed and don't make the ones that we define
invalid. I was also under the impression that our ABNF allowed for
this. If this is not the case, I am strongly for changing that.

Cheers,
Silvia.
