Chart legend title, was Re: [office] Chart legend orientation

[Michael Brauer - Sun Germany - ham02 - Hamburg <Michael.Brauer@Sun.COM>]

Hi,

the current description of the chart:legend element is:

"The <chart:legend> element determines whether or not a legend is 
displayed in the chart. The legend's position may be specified either as 
a relative or as an absolute position. The size of the legend is 
calculated automatically and therefore cannot be set as attribute."

In order to add an optional legend title as described below, I suggest 
that we add the following paragraph to the description:

"The <chart:legend> element optionally may contain a <text:p> element. 
If it is present, it defines a title for the legend."

The change to the schema that is also necessary is already described below.

Best regards

Michael
