A few similar questions (mostly in the now locked Office 2013 preview forum) but perhaps this is best forum to ask.
What is the customui schema/xml namespace for Office 2013 (in order to customize the ribbon)?
For Office 2010, it is <customUI xmlns="http://schemas.microsoft.com/office/2009/07/customui">, For Office 2007, it is <customUI xmlns="http://schemas.microsoft.com/office/2006/01/customui">.
The Office 2013 is nowhere to be seen on the Internet as far as I can see (search?), even though it has now been released.
If somebody has the proper release of Office 2013, my undertsanding is that they can go to customize the ribbon in Word/Excel etc, make a customization, export it and then examine the exported file (e.g. file 'Word Customizations.exportedUI' from Word) and that will show it.
In the Office 2013 preview, it just exported as Office 2010 <mso:customUI xmlns:mso="http://schemas.microsoft.com/office/2009/07/customui">. I assume if somebody with the released Office did that now, they could tell us the new Office 2013 customui?
Thanks for any help on this.
