XSLT 1.0 5.5: the default priority of a single-step match pattern is set by its node test, regardless of an explicit child:: or attribute:: axis. defaultPriority matched the whole pattern string, so attribute::node() fell through to 0 (a name test) instead of -0.5 (a node() node test), wrongly outranking @*. Strip a leading child::/attribute:: axis before classifying the node test. Closes Apache Xalan conformance cases conflictres29 and conflictres30.
