+    fixed parameters and variable arguments following.

+    @see ScFuncDescCore
+
+    @NOTE: the value can't be easily changed. If changed then
+    reportdesign/source/ui/misc/FunctionHelper.cxx
+    FunctionDescription::getVarArgsStart() has to provide some backward
+    compatibility for implicit API stability.
+    The new VAR_ARGS value must be significantly greater than the old
+    PAIRED_VAR_ARGS (2*VAR_ARGS) value, in fact greater than any used number of
+    fixed parameters followed by optional paired parameters.
+
+    @NOTE: also
+    reportbuilder/java/org/libreoffice/report/pentaho/StarFunctionDescription.java
+    uses a hard coded value in StarFunctionDescription::getArguments() for
+    functionDescription.isInfiniteParameterCount() which though looks like it
+    could be easily adapted.
