Not directly AXL related but I figure I'd ask here anyway.. is there still a point to filling out the primaryPhone Tag in a phone? It was used to adjunct licensing some licensing model revisions back, but is it still valid? With CUWL, does it matter if it is set or not?
Yes, it used to be a licensing issue. It shouldn't matter anymore, so it's safe to ignore the tag. It's not even an available option from the web UI anymore. (Actually, I think it was mistakenly left in the UI at one point, and then later removed.)
