[jdom-interest] Using XPath in Multi-Threaded Env

[Rajan Gupta]

Thanks for the response. 
But if were to use XPath is a threaded environment, we are assuming that
in the future the XPath code will not be changed to start using context in
some other way?
Do u have an insight into why Jason Hunter is storing context in a private
variable?

Thanks again
Rajan
