Hi Patrick
I was just suggesting the talk list for more general questions since more 
contributors participate and can benefit from the discussion.
As done with other Quality tools such as Osmose, the best is to link to JOSM. 
This way, validators can look easily at the historic of the object and verify 
for example if a missing member of the relation has been deleted. They can also 
see other objects around and verify if this was a duplicate.
A contributor erased a few hours ago relation 5366432 with an indication that 
relation id=189383 is a complete version with an outer describing the Manoa 
Innovation Center.

My apologies for the noise. I was viewing my question about
the member having a role="" from a technical perspective. i.e.,
"what does software do with that?"

I have just subscribed to talk@ and will move such discussions
there moving forward.

Yes. I completely understand those details. Code I'm writing is
stumbling on "anomalies" in the sample data dumps and I'm
trying to figure out what's the best way to deal with these.

Some I think need correction e.g., relation id="5366432" with
only two members which are marked role="inner". This is an
obvious mistake the correct relation id="189383" has the same
two "inner"s and the proper/expected "outer".

Anyway thanks for your and everyone else's time and advice.
