The XQuery specifications alludes to the fact that XQuery was designed 
in such a way as to be able express queries across various kinds of 
data, including relational databases.

Does this mean that the FLWOR expression was designed to support  
queries that can be performed on relational databases? Was it designed 
to be roughly equivalent to SQL? Given that a relational database has 
some mechanism for exposing XML views on relational tables, is it 
relatively straight forward to convert an FLWOR expressions into SQL? 
Do we expect that relational database vendors will implement XQuery 
processors that directly integrate with their databases in an efficient 
manner?

Thanks,
