> From: Greg Dennis <gregsdennis@yahoo.com> > A singular path should be run-time-determined. If the path returns a single value, it's singular for that data. This works for dinner expressions (comparisons) as well as a base definition for further refinement in normalized paths. Comparisons against multi-results just return false (for now; we may want to expand and define this later). > > This means that there's not a specific subset of the syntax that can define a singular path, but I think that's fine. > I agree that that makes sense for value comparisons. I believe it's also consistent with XPath, https://www.w3.org/TR/xpath-31/#id-value-comparisons ("If an atomized operand is a sequence of length greater than one, a type error is raised.") Daniel
