Behavior for Style like Format ()

It is possible to define a Style that works like a Format element (H1,H2,...). We need to define Styles that works with/like paragraphs. That I can set the cursor in the text, select an style and the whole paragraph is formatted with the selected style.

One problem we have with the Style is the possibility to mix it (overlap). The generated code is not a valid xml.
