Set difference and intersection

These operators are new in XPath 2.0.

The expression E1 except E2 selects all nodes that are in E1 unless they are also in E2. Both expressions must return sequences of nodes. The results are returned in document order. For example, @* except @note returns all attributes except the note attribute.

The expression E1 intersect E2 selects all nodes that are in both E1 and E2. Both expressions must return sequences of nodes. The results are returned in document order. For example, preceding::fig intersect ancestor::chapter//fig returns all preceding fig elements within the current chapter.
