... before we populate the registry. This could apply to menu items, or more generally to other registries. A registry is a tree of items identified by path names. Various code, that need not coordinate, can specify items to attach to the tree, and the merging procedure collects them into a single tree that can be visited. Pathnames imply only an unordered tree. Some visitation ordering must be imposed on the nodes, and can be remembered in preferences for stability between runs, independently of accidents of the unspecified sequence of initialization of file-scope static objects in the various plug-ins. It can be arbitrary -- not constrained to some fixed intrinsic criterion like alphabetical order. Merging consults the preferences, and also updates them if previously unknown items are found and inserted. For now, such unknowns just go to the end of the sequence of siblings, sorted by their path component names.
