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

Makes sense for me.

Matches well with what we have for shapes, and the mapping for
Accessibility API.

BTW - I propose to have the same for sheets in a spreadsheet:
- Same features for Accessible Name/Description
- Sheet names have much more restrictions because of macro access, so
via the Title people can give them names they otherwise can't.
