The optimized query -- it winds up static! -- for your example is impressive, too. https://qt4cg.org/branch/master/xquery-40/xpath-40-diff.html#id-arrow-operator It's great to see "arrow expressions" getting something easily findable in the documentation. "Fat arrow" -- even "broad arrow" -- and "thin arrow" strike me as not being optimal choices of names. Perhaps "parameter substitution arrow" and "function iteration arrow"? "substitution arrow" and "iteration arrow" for short? -- Graydon Saunders | [email protected] Þæs oferéode, ðisses swá mæg. -- Deor ("That passed, so may this.")
