[OAI-implementers] Re: Problem with Repository Explorer

[Hussein Suleman]

hi

i suppose this is a question of interpretation.

the spec says "noRecordsMatch- The combination of the values of the 
from, until , and set arguments results in an empty list"

now, if from>until and both are independently legal dates, then in a 
set-theoretic sense the combination of these parameters results in an 
empty set. thus, the re expects to find "noRecordsMatch".

does this make sense ? or should i be accepting both errors (the other 
being badArgument) ?

ttfn,
----hussein

cc: oai-implementors: if anyone does not agree with this interpretation, 
now would be a good time to mention it :)
