[xsl] Error in XPath expression with IE

[António Mota <amsmota@xxxxxxxxx>]

Hi:

Maybe this is a little of-topic, but i have this problem where the expression

(//Menu)[1]ancestor-or-self::Menu/MenuTitulo

gives a error on some IE browsers 

unexpected token 'eof' found ':'.

while in others work ok. So i think it's because that weirdness of
having the mxxml's working in side-by-side or replace mode.

So i have two questions. 

Can i "force" ie to work in one mode without intervension on the
client computer?

Can i write this XPATH expression withou the use of the axis?

Many thanks and excuse the ot part of this.
