Hello, I have recently started using YSLD plugin of GeoServer.
I really love this feature as it makes me easy to create styles with complex filter functions and does not create unpredicted rules like CSS.
I have noticed that YSLD currently does not support vendor param sortBy for FeatureTypeStyle (http://docs.geoserver.org/latest/en/user/styling/sld/extensions/z-order/syntax.html).
It will be useful if it supports this param. For example I was visualising populations by circle radii in ysld and wanted to put small circles upon large ones.
I can get it around by using WMS's sortby param, but still wish to have it.
Thank you very much
