Re: datasetNamer: using DodsAttrib

Hi Mark,

Are you getting a resulting file at all? From the "Got DAS" messages, it looks
like some of the datasets are getting named (or at least getting to the point of
getting information from the DODS datasets. I'm wondering if the warning is when
it tries to name the directory level datasets using the DodsAttrib namer.
