writing attribute style:background-transparency

[Regina Henschel]

Hi all,

the ODF TC is going to discuss issue OFFICE-3770 [1], which is about the 
attribute style:background-transparency. I'm trying to generate a 
document by LibreOffice, in which this attribute is used. But in all my 
tries I always get draw:opacity or draw:opacity-name (in case of gradient).

Do you know a situation where LibreOffice writes the attribute 
style:background-transparency ?

Kind regards
Regina
