[?] background-position-*

Does anybody know whether background-position-* is now implemented in
FOP?

Example:
                        background-image="cherubino_filigrana12x12.gif"
                        background-repeat="no-repeat"
                        background-position-horizontal="center"
                        background-position-vertical="center"

Many thanks in advanced!
