Mike,
The purpose of a Schema Element Test is to measure whether a given element 
satisfies the schema element declaration of the same name. If the schema 
element declaration specifies "nillable", the element may satisfy this 
declaration by having a "nilled" property that is either "true" or "false". If 
the schema element declaration specifies "not nillable", the element must 
have "nilled" = "false". In other words, the only way in which a "nilled" 
property could cause an element to fail to satisfy its element declaration is 
if the declaration specifies "not nillable" but the element has "nilled" 
= "true". This corresponds exactly to the specification in XQuery Section 
2.5.4.4.

Please let me know whether this explanation resolves your issue.
Thanks,
Don Chamberlin
