So you suggest to keep the internal structure?
That would mean, we will get about 18 additional "LabelFoo" properties
over the time for the still missing fill and line properties.
Then these needs to be done:
A) Implement import of such ODF files, which use the styles of
<chart:data-label> elements for the fill and line properties of labels,
so that this information goes into the internal "labelFoo" properties.
B) Implement export to ODF, so that it writes the "labelFoo" properties
into the styles of <chart:data-label> elements, initially in addition to
the loext:labelFoo attributes.
C) Implement a service for the "labelFoo" properties. (Currently they
are not officially available in the API, although they are visible in
the Basic IDE.)
The problem was not introduced by Gülşah, but this structure was
determined by Kohei Yoshida July 2014 with commit
