Pretty much as it says, strange one this, previously we were happily copying from a BPEL variable into a new variable initialised with a prefixed-literal element. However now, after the bpel:copy has occured the resulting variable contains the correct root element name, but in the original namespace of the 'from' variable, rather than previously where it left the namespace of the root element alone. I hope this makes sense :)
