altLabels in different langauges

Dear,

Example:
<skos:Concept rdf:about="" >
<skos:prefLabel xml:lang="en">peace</skos:prefLabel>
<skos:prefLabel xml:lang="nl">rust</skos:prefLabel>
<skos:altLabel xml:lang="en">repose</skos:altLabel>
<skos:altLabel xml:lang="en">serenity</skos:altLabel>
<skos:altLabel xml:lang="nl">rusten</skos:altLabel>
<skos:altLabel xml:lang="nl">sereniteit</skos:altLabel>
</skosConcept>

Is there a way in SKOS core to indicate that "rusten" is the translation of "repose" and "sereniteit" of "serenity";
that these altLabels belong together?


Regards,


Paul
