java.lang.Object net.sf.saxon.pattern.NodeTest net.sf.saxon.pattern.AnyNodeTest
public final class AnyNodeTest
NodeTest is an interface that enables a test of whether a node has a particular name and type. An AnyNodeTest matches any node.

public ItemType getSuperType(TypeHierarchy th)
NodeTest
In fact the concept of "supertype" is not really well-defined, because the types form a lattice rather than a hierarchy. The only real requirement on this function is that it returns a type that strictly subsumes this type, ideally as narrowly as possible.
