I have input like this:

  . . .
  <topics days="P1D P4D">
  . . .

and in order to get a sequence of dayTimeDurations, which is what I
want, I've had to write

  <xsl:variable name="days" select="tokenize(//topics/@days,' ')"/>
  <xsl:variable name="ds"
        select="(xs:dayTimeDuration($days[1]),xs:dayTimeDuration($days[2]))"/>

This is not only tedious, it only works if I know in advance how many
days there will be, which in principle I don't.  What's the right way
to do this?  I spent rather a long time searching the documentation
without success. . .
