In 11.2.1 <chart:title> we have:

"The text of a title is specified by a child <text> element or a table:cell-range attribute. If a
child <text> element and a table:cell-range attribute are both present, the text specified
by the table:cell-range attribute is used as the title. "

The last sentence is surely not quite right and should be:
"...,the text contained in the cell specified
by the table:cell-range attribute is used as the title"
or something like that.

Moreover:
"By default, the content of a child <text> element is displayed as the title."
What does "by default" mean here? If there is no child <text> element nor a table:cell-range attribute then there cannot be any title obtained from such a child element.

Finally,
in ODF 1.1 the attribute was called table:cell-address, are we really changing that to table:cell-range? SInce table cell range can contain a list of cell address ranges, how is the title derived from such a list?
