XACML: ex-act-mul or zak-mul ?

a pronunciation question:

XACML:  ex-zak-mul  or  zak-mul ?

As a hint, ask yourself how you really pronounce XEROX. (and yes I suppose I'm
leaving myself open to some flamage from non-native-ahmurkan-english-speakers)

ps: a co-worker of mine at xerox pronounced "xerox" quite clearly as
"zee-rocks". I seem to recall he was speaking a southeasternUS dialect of
american english.
