just poring over Kay's book, filling in the gaps, and in
the section for xsl:message, there's an example that's selecting:
//sales[string(number(current()))='NaN']
just to make sure, i'm assuming the "current()" part is
redundant, since number() will use the string-value of the
context node if there is no argument. do i understand that correctly?
Inside a predicate, current() does not select the same thing as ".".
So the current() here is not redundant. But it is wrong: the example as
written won't do anything very useful, because the value of the
predicate doesn't depend on the context node.
