I’ve searched high and low through all the documentation I could find, and I still don’t know: What are the legal values for the "id" parameter?
The documentation and the source code both say "Any valid folder location containing the Ditto source code with a trailing slash". But that can’t be right.
My impression is that this is supposed to be a user-defined, unique string that’s used to link instances of cooperative snippets together. Thus I’d expect the rules to be "any postive integer" or "any unique text string consisting of only letters, numerals and underscores", or something like that.
So what indeed are the rules?
