This isn't quite right - a label can be used in one BGP (a stronger condition) The text in 5.1.1 is [[ A label can be used in only a single basic graph pattern in any query. ]] and that means no reuse across GroupGraphPatterns Putting all the restrictions in one place is a good idea. I'll do that. Andy > > > Any other opinions on any of the points above? > > Cheers, > Axel >
