[xsl] redundancy in string(number(current())) = 'NaN' ??

["Robert P. J. Day" <rpjday@xxxxxxxxxxxxxx>]

  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?

  if so, i assume that that was just put in for aesthetics.
