[thredds] TDS Catalog Validation Service



Greetings,
I have a question about validating the semantics of a THREDDS catalog. The attached catalog contains a number of thredds:catalogRef elements. The urlPath attribute for these should be able to be used to resolve the individual catalogs. Is there a validation for that similar to using the built in Catalog Validation service that come rolled in the TDS? I tested the attached catalog against the service at motherload.ucar.edu: 

http://motherlode.ucar.edu:8080/thredds/catalogServices?cmd=validate&catalog=http://ndp.opendap.org:8080/opendap/data/catalog.xml
And it passed, but I don't imagine it attempted to check down the catalog hierarchy. 



Any ideas?



Thanks,

Nathan
