[NTG-context] XML xmldoif struggle!

[Geert Verhaag]

Hoi Pablo,

Thanks for your prompt reply!

The output Euro set! is printed always, it doesn't matter whether I put 
EURO or DOLLAR first?!

Also I can't find any clue on the suggested page 49 of xml-mkiv.pdf 
manual, sorry!

By the way, in my document it still doesn't seem to work!

I'm afraid all this is far too complex for me! The documentation simply 
isn't meant for beginners like me, sorry!

Regards,
Gerard
