net.sf.saxon.expr.FunctionCall
net.sf.saxon.functions.SystemFunction
com.saxonica.extra.DynamicFunctionCall
This class implements the extension function saxon:call(), which calls a FirstClassFunction previously set up using saxon:function(). The first argument is the FirstClassFunction object, the remaining arguments are the parameters to be supplied in the call.
