To offer a suggestion, order the stack from bottom (lowest number) to top (highest). Require that bottom of stack be element index zero. My yang constraints are a bit weak but I believe you can construct an XPath that requires that a node of index 0 must be present. The above two suggestions don't help with the issues of needing to sort the list by index in order to generate the stack, but it does at least remove any possible ambiguity about the critical bottom of stack semantic. -- Jeff
