CSS z-index in xhtml and SVG in object

The text 'Maybe text for navigation menu.' should be displayed on top, because it is fixed positioned an has the highest z-index in CSS. Try to scroll the page. The correct behaviour is especially importent for css-Layout with position: absolute and position: fixed. Else it will be possible, that the menu of the project becomes inaccessible with a wrong overlapping SVG-object.

Maybe logo or text for navigation menu.
