Description

According to the XPath specification, any prefix which maps to the same URN is
equivalent. If a prefix is remapped to the same URN then lack of string
interning somewhere causes subPartMatchNS in
org/apache/xapth/patterns/NodeTest.java to fail since it uses == comparason
not .equals() comparason on the strings. Similarly if two prefixes map to the
same URN the same problem occurs.
