A FAQ: use something like
<xsl:for-each select="//tracker-id[not(.=preceding::tracker-id)]">

This is the traditional solution; Steve Muench has just told me about a
brilliant alternative using keys:

<xsl:key name="tid" use="tracker-id" select="."/>


I hope Steve will forgive me for announcing this discovery before he does,
I'm quite excited by it because it gives much better performance.
