[Mapnik-users] Question about Rule, filter and zoom layer

[francescobocca...@libero.it]

Hi to all,
i'd like to speed up my rendering tiles with mapnik and i need your help:
I have many rule that use the same filter for a difference zoom levels like 
this:

 <Rule>
                <Filter>[BOYSHP] = '3' and [COLOUR] = '3,4,3' </Filter>
                &maxscale_zoom16;
              &minscale_zoom18;
                <PointSymbolizer allow_overlap="yes" file="&icons1;/bysp66C.
png" type="png" width="20" height="46" />
           </Rule>

           <Rule>
                <Filter>[BOYSHP] = '3' and [COLOUR] = '3,4,3' </Filter>
                &maxscale_zoom12;
              &minscale_zoom15;
                <PointSymbolizer allow_overlap="yes" file="&icons1;/bysp66CS.
png" type="png" width="16" height="36" />
           </Rule>

My question is: Can i "merge this kind of rules in one using something like:

 &maxscale_zoom16;
              &minscale_zoom18;
OR 

 &maxscale_zoom16;
              &minscale_zoom18;


Thanks


Francesco
