[XSLT 2.0] Suppression des doublons

Bonjour, je cherche à supprimer les doublons, mais je suis dans un cas ou je n'y arrive pas (en fait, ma solution fonctionne sur certains XML, mais pas tous ceux que j'ai à ma disposition ... C'est donc faux).

Comment expliquer mon probleme ... J'ai des noeuds "unit", que je tries par ID. Suite à ça, je dois créer une nouvelle structure dans unit, "unit/anticipatedStance", qui ne tolère pas les doublons de "unit/location".

Je cherche donc à avoir des locations/point distinct pour une même unit (un même unit c'est selon son ID).

Ma ligne XSL qui me permet de trier est la suivante. Or, dans le cas du XML fourni, ca ne fonctionne pas.
(Ce morceau se trouve dans <xsl:template name="creationAnticipatedStance_Ownsitrep">)

Code:

<xsl:when test="(not(current()/@context) or current()/@context!='STC') and location and location[not(./point=preceding::*/point)]">

Voilà ce que j'obtiens
