Hi Americo,
Does this means that doing something like
<xsl:if test="$foo=$foo"> might return false??
Yes, if the post() function is not idempotent (if it may return
different results each time that it's used with the same arguments).
Actually, test="$foo = $foo" can return false already as it is,
e.g. if $foo is set to NaN. Does this mean that the "constant" NaN
isn't idempotent (thinking of it as a function of zero arguments)?
Or to put it another way, number() is not idempotent if its argument
is "snizzlfritz" ... right?
