Hi Mike,

I've tried to reproduce this but get no root elements to select from during the import process.  Is it possible that the XSD pasted here is different from what you're using?

(This View abstraction turns out not to be the problem -- I query the Source via the Execute'd VDB with the same outcome.)

Is there something goofy with the equality operator against XML data? Is there flag that needs flipped on these attributes? I went with the "string" mapping on the 'XML Schema as Relational Source Model' dialog wizard (pane 4 IIRC). Oughtn't I have? I also changed XML node names that might have been SQL keywords ('name' -> 'fullname') but no dice...
