str:tokenize is in exslt.  I used it as an example because you can test
with it.  It takes a string, and returns a nodeset after tokenizing the
value, i.e. the above would return
<token>bob</token><token>smith</token>

If that's the case, I using the following gives junk output, which
doesn't seem correct:  <xsl:value-of select="str:tokenize('bob
smith')[2]"/>

It's in exslt.  It's a simple example that returns node-sets.
