Re: [office] Drawing page names (Re: [office] OpenDocument TC MeetingMinutes 2006-02-13)

Hi David,

thanks for bringing this topic to our attention again. I have asked 
Christian Lippka, who is from the OOo graphics team, for his opinion. 
That's what he thinks:

To me, that sounds reasonable.

Best regards
