I care, but I dont totally understand the issues (I'm WSDL illiterate). I
want to be able to send back any reasonable HTTP code for uncommon
conditions (eg. server segfaults, out of memory), but as far as I can see
you both think that should be OK.

However, apache returns 500 server errors when something internal goes
wrong, and as my main HTTP mechanism is apache modules its out of my to
control to return a non SPARQL 500 if something really bad goes wrong.
OTOH I could argue that at that stage its just not a SPARQL service, as
its not capable of processing anything at all.
