I was wondering the same thing, just to sidestep the "who hands out IDs" question. Just using a string like "EDB v" + something would probably rule out collisions in practice. To be more formal about it, something like the tag URI scheme [0] could be recommended. Nothing at runtime would have to know or care about tag URI syntax; it would just match a string with a fixed opaque prefix and some suffix. The scheme gives the developer an easy way to construct a meaningful and reliably non-colliding string. Surely loading libraries isn't a hot enough operation to begrudge a strcmp.
