Nice!

Also nice. Maybe VariableContext interface should have a put() method on it
as well as the get() so that
XPath.setVariable( "name", "Here's Johnny" );
could under the covers call getVariableContext().put( "name", "Here's
Johnny") without the developer having to explicity create a VariableContext
etc.
Then maybe a different method like bindVariable or replaceVariable() or
something could turn the variable expression into a literal value as you
suggest.
