yes that's reasonable, but the LIBKML driver should already do that :


OGRStyleSymbol *kml2symbol (
    IconStylePtr poKmlIconStyle,
    OGRStyleSymbol *poOgrStyleSymbol)
{

    if (!poOgrStyleSymbol)
        poOgrStyleSymbol = new OGRStyleSymbol (  );

    /***** id (kml icon) *****/

    if ( poKmlIconStyle->has_icon (  ) ) {
        IconStyleIconPtr poKmlIcon = poKmlIconStyle->get_icon (  );

        if ( poKmlIcon->has_href (  ) ) {
            std::string oIcon = "\"";
            oIcon.append ( poKmlIcon->get_href (  ).c_str (  ) );
            oIcon.append ( "\"" );
            poOgrStyleSymbol->SetId ( oIcon.c_str (  ) );

        }
    }

And the reverse code also exists.
