Fair enough.  They serve as the canonical test suite for "classic
Turtle" support, and as an implementer I will keep them around for that
purpose regardless.  I suspect others will as well.

I don't care much if they are not included in the official test suite,
but IMO it'd be better if they were.  Despite not being a
recommendation, in reality Turtle is an established standard with a wide
implementation base and large amounts of existing data, and that test
suite has served for years.  Perhaps the new ones exhaustively cover the
same cases, but it's not immediately obvious if so.

This could probably be more prominent, perhaps in a dc:comment within the Manifest.

You're right, both new suites do work with that URI.  I was mistaken
that the other *required* a different one, I just happened to run it
with a different one and it worked.  Actually it does not care about the
base URI at all and will work correctly with anything.

The authority "example" with no TLD seems odd to me, but whatever.
