Sigh, sorry, I used the wrong names. Fallback as specified in SE 1.1 cannot be used. What I need is an optional default default value. <Function name="env"> <ogc:literal>threshold</ogc:Literal> </Function> would return the "threshold" variable, or null if not found, whilst: <Function name="env"> <ogc:literal>threshold</ogc:Literal> <ogc:literal>0</ogc:Literal> </Function> would return the "threshold" variable, or 0 if the variable is not found. Does it make sense?
