[NTG-context] Using \commalistsentence in combination with \processcommacommand... I'm going mad?

[NTG-context] Using \commalistsentence in combination with \processcommacommand... I'm going mad?

Hi list. This is probably the wrong thing to do. However, it's what I have
been trying:

% MWE %%%%%%%%%%%%%%%%%%%%%%
% Registro de autores
\definenamespace[autores][
  type=module,
  name=autor,
  command=yes,
  parent=autores,
]

\define[1]\AutorNombreApellido{\edef\currentautor{#1}{%
  \doifsomething{\autorparameter{nombres}}{\autorparameter{nombres}\space}%
  \doifsomething{\autorparameter{apellidos}}{\autorparameter{apellidos},}%
}}

\define[1]\ListaAutores{{\AutorNombreApellido{#1}}\space}
\define\autoresListaH{\processcommacommand[\documentvariable{autores}]\ListaAutores}

\defineautor[autores][rol={autor}]
\defineautor[andi][autores][nombres={Andrés Conrado}, apellidos={Montoya
Acosta}]
\defineautor[soni][autores][nombres={Sonia Amparo}, apellidos={Rodríguez
Rodríguez}]
\defineautor[sofi][autores][nombres={Sofía}, apellidos={Parra Albarracín}]

\startdocument[autores={andi,soni,sofi}]

\commalistsentence[\documentvariable{autores}][{;\space},{\space\letterampersand\space}]

\blank[big]

\commalistsentence[\autoresListaH][{;\space},{\space\letterampersand\space}]

\stopdocument

%%%%%%%%%%%%%%%%%%%%%%%%%

As you may see, I'm trying to process a list of authors, based on the
examples in https://wiki.contextgarden.net/Command/startdocument and
https://wiki.contextgarden.net/Command/commalistsentence. But this is
getting convoluted and I'm convinced there must be an obvious simpler
solution I can't seem to find.

- The output comes out `Andrés Conrado Montoya Acosta, Sonia Amparo
Rodríguez Rodríguez, Sofía Parra Albarracín,`
- I want `Andrés Conrado Montoya Acosta; Sonia Amparo Rodríguez Rodríguez &
Sofía Parra Albarracín` as the first line in the output: `andi; soni & sofi`

I think I am doing something wrong, because probably it's possible to set
up the \processcommacommand to act in the same way as the
\commandlistsentence? (I'm guessing this is what I want) But I can't seem
to find how.

Also consulted:

https://wiki.contextgarden.net/ConTeXt_and_Lua_programming/Tutorials/System_Macros/Action_Processing

-
https://wiki.contextgarden.net/ConTeXt_and_Lua_programming/Tutorials/System_Macros/Comma_Separated_Lists

Something there should help but I'm not really sure what. Any clue would be
greatly appreciated. Thank you very much.

Take your choice ... two approached, one a bit mkii-ish, the other more 
lmtx-ish (both ok, all depends on specific needs)
