catalog schema question: variable element

[Ethan Davis]

Hi Darren,

The mixed content for <variable> was added in InvCatalog version 1.0.1 
(our current stable release). Looks like you are using 1.0.

I'm afraid our announcement of InvCatalog 1.0.1 was rolled up into a TDS 
release, so it wasn't very visible. AND our documentation didn't all get 
upgraded to reference 1.0.1. I just fixed the schema URL below in your 
schemaLocation line, 
http://www.unidata.ucar.edu/schemas/thredds/InvCatalog.1.0.xsd, to point 
to the 1.0.1 version. (All changes to the 1.0 line will be backward 
compatible. Boy, schema and namespace versioning isn't pretty.)

Sorry about that. If your parser is using the schema at that URL it 
should work now. If a local copy, you'll have to grab the 1.0.1 version.

Ethan
