I am baffled as to what's wrong with this case, but I observe that SQC (2.2) also complains about test4, but not test1 or test2 or test3. Ah, I see the problem -- it's the vexed "pointless occurrence" 'feature'. Xerces and SQC are right, the rest of us (including XSV) are wrong. When a sequence has min and max of 1 and is embedded in another sequence, you have to pretend it's not there, so you're actually comparing (a,b,d?) with ((a|b|c)*,d?) which is a three-versus-two comparison, which fails. Sigh. As mentioned by someone in the thread you started, fixing this is _high_ on the list of planned changes for 1.1. ht -- Henry S.
