This relative URI is appended to the "base" URI, which is the location of your catalog file, unless xml:base is defined for the catalog.

Relative paths are resolved using the location of the document as the "base" uri, which means it won't draw from a repository anyway.  Consumers will need to provide a namespace locator to get these to resolve, which would probably ignore anything specified in schemaLocation (i.e. it's probably working off the publicId's, just like your catalog).  This seems like a bug in Eclipse, although that _is_ the location of the schema, so I could see it not being a bug too.

I'd root around in the wst code base to see if there is some configuration setting you can use to control what gets populated there.  Another option is to just leave it out.  Sorry I couldn't be more help.
