You mean an additional example that use this additional binding? This may be difficult to add since the current example in this schema is a root one and I can't put multiple root example. Is it acceptable to add a dummy opp table with some comments explaining the dummy node is not supported in the current compatible? (apq8096) > > Best regards, > Krzysztof >

But it's not a problem the real important patch in the series is the first one.
