org.pdf4j.saxon.type.TypeHierarchy.relationship()
Determine the relationship of one item type to another. @param t1 the first item type @param t2 the second item type @return {@link #SAME_TYPE} if the types are the same; {@link #SUBSUMES} if the firsttype subsumes the second (that is, all instances of the second type are also instances of the first); {@link #SUBSUMED_BY} if the second type subsumes the first;{@link #OVERLAPS} if the two types overlap (have a non-empty intersection, but neithersubsumes the other); {@link #DISJOINT} if the two types are disjoint (have an empty intersection)
