Indeed. I can generate it from scratch. Fortunately LibreOffice can read 
the chart too, if I remove the <table:table-columns> element. So older 
versions would be able to read charts, if the element is removed in a 
newer version.

I was not able to generate such document. I have tried it with report as 
text document, report as spreadsheet and with the old kind of reports 
from OOo2.4.3. I always have got only <table:table-column> elements.

I think it is redundant. I consider to propose, that the element is 
removed or at least deprecated in ODF 1.3.
BTW, the OASIS-issues are
