That was a good tip. I found my error, that the property was not 
actually set at the object and therefore the default 0 was used. But 
after fixing that, I still got a 0 on opening.

I then used test files, where I removed 'writing-mode' attributes. I 
have found, that the 0 comes from the 'style:writing-mode' in the 
paragraph properties inside the graphic style. From point of standard it 
is correct that it takes precedence over the 'writing-mode' in the 
graphic properties inside the graphic style.

I will try now to change ContextFilter() method to get a suitable markup 
on saving. I need to be careful to not conflict with frames. But I am 
hopeful to find a solution.

Kind regards,
Regina
