[Fwd: Re: [office] Drawing page names (Re: [office] OpenDocument TCMeeting Minutes 2006-02-13)]

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

Dear SC members,

in our recent TC calls we discussed that drawing page names currently 
have to be unique (see section 9.1.4 in the recent ODF 1.2 draft), while 
it in practice sometimes may happen that two pages have the same name.

We discussed several option how to deal with this situation, and the 
last idea is to

- keep the uniqueness constrain for drawing page names,
- but to add <svg:title> and <svg:description> elements to pages.

This allows authors to assign the same title to two or more pages if 
they really want to do so for whatever reason, while the names still 
would be unique. It further allows to assign descriptions to pages, what 
is also not possible at the moment.

I accepted an action item to ask you whether this enhancement would be 
okay for you.

Malte mentioned that we may add a title and description also to 
spreadsheet tables. While this goes beyond the original request, it 
would be good to know your opinion on this as well.

Best regards

Michael

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.

Malte.
