I've setup a node mapnik server to render some tiles for polygons. The application I've built to call out to these tiles is in Leaflet
An example of a current mapnik styling rule is below
<Style name="pubLands">
<Rule>
<Filter>[simple] = 'blm'</Filter>
<PolygonSymbolizer fill="#e3cc00"/>
<LineSymbolizer stroke="black" stroke-width=".1"/>
<TextSymbolizer size="5" fill="black" face-name="Helvetica Black Regular" halo-fill="#DFDBE3" halo-radius="1" wrap-width="20">[detail]</TextSymbolizer>
</Rule>
</Style>
Features within this rule are being styled at all zoom levels etc. I would like to only show labels at my map's zoom levels of 13+. How can I modify the style.xml to only label above a certain zoom level, in this case a Leaflet zoom of 13+?
