QuickAccessToolbar and Ribbons XML

[Louverril]

I am trying to achieve the following :
1. No Access Ribbon
2. Uncustomisable Quick Access Tool Bar containing an UNDO button

I can achieve 1. Buy putting this in the USysRibbons table
<customUI xmlns="http://schemas.microsoft.com/office/2006/01/customui">
<ribbon startFromScratch="true">
</ribbon>

</customUI>

And adding the ribbon name to the Access options.

But if I do this I then lose the QuickAccessToolbar.

I’ve tried to find help and played about to add the QAT to my code, for
example
<customUI xmlns="http://schemas.microsoft.com/office/2006/01/customui">
<ribbon startFromScratch="true">
<QuickAccessToolBar>
</QuickAccessToolBar>
</ribbon>

</customUI>

But I get an error concerning the third line :"...QuickAccessToolbar' is
unexpected according to content model of parent element". I’ve tried QAT
instead of the full name and tried putting the QAT after the ribbon tags but
no luck.

Has anyone got any ideas?

Thanks

Lou
