+ * The two-argument version:

+ * is rewritten into:

+ *
+ * The distinct-values() call ensures the node deduplication and sorting,
+ * although it fails in the case that URIs resolve/directs in some way to
+ * the same document. Some of those cases can be solved by wrapping the
+ * whole expression with a node deduplication(conceptually the-for-loop/.).
+ * One advantage with distinct-values() over generating traditional node
+ * sorting/deduplication code is that the latter contains node sorting
+ * which is uecessary and can be hard to analyze away. distinct-values()
+ * doesn't have this problem due to its narrower task..
+ *
+ * This works without problems, assuming XTRE1160 is not raised and that

+ * one must cater for this.
+ *
+ * In addition to this, both signatures has its first argument changed to
+ * type <tt>xs:string*</tt>, in order to generate atomization code.
+ *
