I was thinking more along the lines of Mozilla defining for instance a spellchecker interface. Just some interface in which you supply a target language and a word and the spellchecker will return a list of recommended substitutions if it doesn't know the word. Now, if I would write a component and I would need a spellchecker, I would like to ask the componentmanager if there is *any* class implementing that interface. And if so, just use the first one available. The user could than quite easily remove a certain implementation of the spellchecker for another one, without me having to put all possible CIDs that could implement this interface into my component and check if any of these CIDs is available. (And hoping that after I publish my component no new spellcheckers come available). I hope this clarifies my question. (BTW: it is only an example) Greetings, Marco Bosch
