Regina has prevented several errors from getting into future drafts! Thanks:
some editorial remarks:
new 19.575.2: height of --> width of
..., or registered in accordance with [.
There is something missing.
new 20.9 chart:data-label-series
The text has wrong font face.
The part "The attribute is evaluated for ..." is missing.
The part "The defined values for ..." is missing.
The term "series name" is not defined. But I think, we might fix that in a later version, because I think, that there is no problem in the common understanding of "series name". A similar term is used in the description of <chart:legend> and there it is neither defined. The source of "series name" is the attribute chart:label-cell-address of the <chart:series> element and that has data type cellRangeAddressList.
Correct as suggested.
