--- Comment #12 from Gilles Caulier <caulier.gilles at gmail.com> ---
Kavish,

This is an example how LightRoom work to plug tag hierarchies to XMP Dublin
Core :

   <dc:subject>
    <rdf:Bag>
     <rdf:li>Fosstun</rdf:li>
     <rdf:li>Places</rdf:li>
     <rdf:li>Torpa</rdf:li>
    </rdf:Bag>
   </dc:subject>
   <lr:hierarchicalSubject>
    <rdf:Bag>
     <rdf:li>Places|Torpa|Fosstun</rdf:li>
    </rdf:Bag>
   </lr:hierarchicalSubject>

It split hierarchy as keywords and store full tags path in
lr:hierarchicalSubject

This is how Microsoft must do. In dc:subject we must store only selected
keywords, as in old IPTC, not the full path. This is how digiKam work
currently, and i don't want to change this, for compatibility with other photo
management programs that we have already tested here, ad Aperture for ex...

Note that Microsoft store full tags path in MicrosoftPhoto:LastKeywordXMP
instead of  lr:hierarchicalSubject. Each program use a dedicated XMP namespace,
as also digiKAm wich have dedicated one where you can find the full Tags Path.

I think with my last commit your problem must be fixed, because a wrong XMP
data container have been used to store Tags Path in
MicrosoftPhoto:LastKeywordXMP.

In others words, i will not perform more change here...
