thanks, I'll add that.

Nice tutorial!
Do you have that information handy? If you do then it would be great to
have it, as far as what I'm trying to do is concerned. I'm unclear how
it's best to present it though. Jena's regression  tests have this sort
of format:

# Variables:
?b ?y .
# Data:
?b <anon:cdedfd:eea1faaa34:-8000> ?y "11" .
?b <anon:cdedfd:eea1faaa34:-8000> ?y "12" .
?b <http://never/bag> ?y "21" .
?b <http://never/bag> ?y "22" .

there is code that tests the expected

bNode-isms,
number or rows etc)
]]

- so I guess that detects bnodes.
