Re: Editorial thread for BGP matching

I propose to have an explicit text to present the reader the  
alternative semantics by Pat in a simple way, immediately before "As  
an example of a Basic Graph Pattern:", as follows:

"In the case of simple entailment, if the scoping graph G' is such  
that it does not share blank nodes with BGP, then the above  
definition can be simplified to use a standard RDF merge instead of  
an OrderedMerge."

I'm sure Andy can find a nicer formulation...
