Excellent ideas. I will package up a tiny example and post to libyang. I am using yanglint 2.0.200.
Since I'm starting from an example that is in RFC 9195, it is easy to build a small example and package up an expect script to show the issue. Regards, -scott.

I have run into a number of validation issues over years and generally first try to validate that my understanding of YANG is correct and, if unsure, I'll ping the NETMOD list (note: there are many YANG subtleties, such as the recent discovery that a module needs to be "implemented" in order for its features to be defined). Otherwise, I submit an Issue to the `libyang` GitHub issue tracker, typically containing the smallest possible module (or number of modules) demonstrating the issue, while also pointing out all relevant facts (e.g., foo is implemented, bar is defined, RFC 7950 Section X says this, etc.). Radek and Michal are pretty good with providing a response in 1-2 business days. Sometimes my YANG-understanding is challenged, at which point we bring it to the NETMOD list. FWIW, `yanglint` recently switched from the 1.x to the 2.x code base. A number of regressions were introduced at this time (resolved now, at least the ones affecting me) but, nicely, the 2.x code catches some issues that the 1.x code never did (it's a better validator). The CLI changed some, and I'm now very careful to ensure all modules that need to be implemented are, and that all features that need to be defined are. I now explicitly disable all features for implemented modules when no features from it are needed. I find that the new 2.x is picky, in a good way and that, after painstakingly working through each issue, all my validation tests are passing now.

Using yanglint, I load all the yang necessary and then load the data from either the xml file (read-only-acm-rules) or the json file (acme-router-netconf-diagnostics). I get a similar error for both... data -t data -f xml acme-router-netconf-diagnostics.json libyang[0]: Node "instance-data-set" not found in the "ietf-yang-instance-data" module. (path: Line number 2.) YANGLINT[E]: Failed to parse input data file "acme-router-netconf-diagnostics.json". What is the best tooling to use to validate the instance data? What tooling was used to validate the contents used in the examples? I'm trying to determine if this a yanglint issue, user error, or I'm just using the wrong tool.
