Hello David,

When I was trying to fix the the custom slide show feature in kpresenter I 
think I found a problem in the opendocument spec.

Background:

In 9.1.4 Drawing Pages there is defined that a page name can be set by using 
the draw:name attribute. It also says that if it is used it has to be unique. 
Also there is a unique draw:id attribute for a page.

Problem in KPresenter:
In kpresenter it is possible to have the same name for different slides which 
I think is good as the user can do so if he wants. 
The problem is that in 9.11.6 Show Definitions it is defined to use the 
draw:name of the page as reference to the slides used in custom slide show.

Problem in OOo-impress:
If you name Slide 1 "page1" and you save and reload the document it will say 
"Slide 1" as name for the slide. This is because OOo-impress uses pageX as 
the default when none is there.
So you can trick OOo-impress to generate 2 times draw:name="page3" if you set 
no name for slide 3 and set the name for slide 2 to page3. If you do so the 
custom slide show feature will no longer work as expected. (No bug reported 
yet.)

To solve the problem of having such problems in the first place I think the 
OpenDocument spec should be changed to use draw:id to identify the different 
pages instead of the draw:name as the draw:name can changed by user input. 
Also the draw:name should not have to be unique. 

Can you talk about this in the OASIS OpenDocument Group please? If you need 
more information you know how to find me :-).

To solve this problem for kpresenter 1.5 I will add a koffice:name 
additionally and will use the draw:name as OOo-impress does at the moment.

Have a nice day,

Thorsten
