Good idea to check that. I see the following two tests in that CITE doc
which check for MissingDimensionException:
* When a layer that has a dimension without a default value is requested
without supplying the dimension parameter, the response is an exception
with code=MissingDimensionValue.
* If the dimension decalaration does not include a default value, a request
without a TIME parameter produces an exception with
code=MissingDimensionValue.
Neither of these sound like they're testing the nearest-value behaviour.
So I guess it's still be bit of spec tea-leaf reading.
