Yes. That's why symbol expressions can be parametrized in the
SymbolInstance (which is in the layer definition). See the
ParameterOverrides element. In any case, this doesn't matter for the
ScaleX and ScaleY since those are defined in the SymbolInstance which is
already part of the layer definition.

So we agree? :). I believe that with the schema as is, the UI can
determine enough about the symbol to make things easy for the user (not
necessarily for the programmer).
