still not completely happy having to keep a separate xml dom, however, ther=

    a check elements with the same id aren't existing should be done

/trunk/KDE/kdelibs/plasma/svg.cpp
<http://svn.reviewboard.kde.org/r/5495/#comment8159>

/trunk/KDE/kdelibs/plasma/theme.cpp
<http://svn.reviewboard.kde.org/r/5495/#comment8158>

    i wonder how much is the benefit vs cost of caching this?
