java.lang.Object | +--net.sf.saxon.pattern.NodeTest | +--net.sf.saxon.pattern.CombinedNodeTest
A CombinedNodeTest combines two nodetests using one of the operators union (=or), intersect (=and), difference (= "and not"). This arises when optimizing a union (etc) of two path expressions using the same axis. A CombinedNodeTest is also used to support constructs such as element(N,T), which can be expressed as (element(N,*) AND element(*,T))
