Again, thanks for the detailed responses.

Should I interpret no response as you don't agree, editorially, and  
that there won't be any changes?

Same here as above. At least the missing "of" should be added.

Ah, just so. No idea why I suggested otherwise! :(

Which one, though? You keep saying "they're in the protocol" -- if  
so, why not say *which* error in the protocol spec would be used for  
*this* case? And for all the other cases? Leaving the reader to go  
and look, when there could be a hyperlink, seems less than ideally  
useful.

No. I was simply asking what the difference is between a "SPARQL  
Query string" and a "SPARQL query" is -- the spec (IIRC) uses them  
sorta interchangeably, which I find distracting.

Did this one get fixed?

Heh, well, I don't agree, but I guess that's the end of that. :>

I agree that there is a distinction here; I don't believe that the  
distinction is made explicitly enough.
