...changed from old-style with 5d1ad167
"fdo#46808 Convert chart2::FormattedString service to new style."  The
CharacterProperties* services dropped there are property-only old-style
services, so only serve documentation purposes anyway.  Ideally, the new-style
service would offer interface attributes for the relevant properties (and likely
not implement XPropertySet at all), but so be it for now...
