Classification according to TSCP-standards

In Writer, Calc and Impress now there is a Classification tool bar that allows you to choose the classification level. Choosing the classification level will result in an info bar, and in Writer (depending on the level) also in a watermark and a field in the header and footer, all showing the level of classification (Non-Business, General Business, Confidential, Internal Only). The classification is based on the Business Authentication Framework (BAF) policy and stored in the document properties.
