Dear ConTeXt folks,


I am trying to customize the reference line in a letter.

```
$ context --version

mtx-context     | ConTeXt Process Management 1.01
mtx-context     |
mtx-context     | main context file: 
/usr/share/texmf/tex/context/base/mkiv/context.mkiv
mtx-context     | current version: 2017.05.15 21:48
```

The example from Wolfgang’s `correspondence.pdf` [1] doesn’t work for me.

```
\setupletter
   [name={Joe User},
    date=\currentdate]

\setupletter
   [list={name,date}]
```

Only the date is shown in the reference line.

The solution from chapter 9 also does not work. Still only the date is 
shown.

```
\setupletter
   [name={Joe User},
    date=\currentdate]

\setupletterstyle[reference][list={name,date}]
```

Do I need to create a new customized reference line to add other fields 
next to the date to the reference line?


Kind regards,

Paul
