Yes, this functionality is unavailable for vendoroptions (Functions in
general do not work for vendor options). As a workaround, you could provide
several variants of your style and refer to them by name, or use the
SLD_BODY or SLD (url to an SLD) query parameters to provide dynamically
generated SLDs from outside of GeoServer.
