It's generally easiest to do it top-down, I think.

Something like this:

<xsl:for-each select="tokenize(., $sentence-delimiter)">
  <sentence id="{position()}">
    <xsl:for-each select="tokenize(., $phrase-delimiter)">
      <phrase id="{position()}">
        <xsl:for-each select="tokenize(., $word-delimiter)">
          <word id="{position()}">
            <xsl:value-of select="."/>

I think you just need position() as shown above.

Sometimes you need to work bottom-up if the "sentences" can't be recognized
until you've identified the "words", for example if you want to avoid
treating "." as ending a sentence if it appears in a number. You're then
sometimes in the domain of positional grouping: create a long flat list of
words, and then group it into sentences using some kind of test applied to
the individual words.
