Thank you David,

I came up with the following key and it works now:

<xsl:key name="ttStyle"
match="/office:document/*/style:style
       [child::style:properties/@style:font-name=
        /office:document/office:font-decls/style:font-decl
          [@style:font-pitch='fixed']/@style:name]"
use="@style:name"
/>
