Adam, and how is said tool going to start in the first place?  Without
meta-data, there is a limit to what the tool can do.  Basically, it would
have to operate relative to the URL provided to it.

As for the particular examples you gave, those carry semantic meaning that
would require more specification that is contained in the URI syntax.
Although those would be desirable, I don't know that we want to including
that kind of semantic specification in the URI.

Tim's URI schema supports your operations when combined with with a semantic
layer, which can be implied or meta-data based.

That does not require the kind of semantic your earlier operations require.
The verification content can be relative to the URI provided to the tool.
