Re: Datatypes input: summary of responses so far

Hi Geoff,

Phew, you guys do make work for me :)  How do I interpret this response?

It says, prefer tidy, if the rdf/xml parser were to transform all literals 
into a b-node structure on input.

We have considered that option, and basically rejected it on the grounds it 
would change the interpretation of pretty much all existing rdf/xml.

I think I hear you preferring tidy and, like the WG, looking for ways to 
wriggle out of the implications of that choice.  This is exactly what has 
kept the WG embroiled for so long.  As it stands however, we have not found 
a satisfactory solution and you have not given us a clear answer to our 
question.

If you had to choose, A or D, which would it be?

Brian
