For accessibility purposes it is not sufficient to read out the data of
one entire table. A chart may have several data series represented as
<chart:series> elements. Each series can point to a separate cell range
using the chart:values-cell-range-address attribute. Additionally, also
categories and other elements of a chart may point to individual cell
ranges not necessarily part of the same table nor adjacent.
