RE: Schema aware XPath 2.0 doubt
Yes, this would succeed if element x were validated as an element of type xs:date. The reason is that operators like "gt" that expect an atomic value, if given a node as an argument, will automatically "atomize" the node. This extracts the typed value, which in this case is an atomic value of type xs:date.
