[NTG-context] xml manual typo

I am reporting a typo in the MKIV XML-manual. It can put one on the wrong track. Section 3.7 Setups: \xmlsetup{name}{node} expands setup name and pass node as argument Note that name and node in the parameters are interchanged. It should read: \xmlsetup{node}{name} expands setup name and pass node as argument Hans van der Meer
