[NTG-context] new layer for letter

[Peter Münster]

Hello,

How can I create a new layer with the letter module?

I've tried this, but it does not work:

--8<---------------cut here---------------start------------->8---
\usemodule[letter]
\defineletterlayer[test]
\defineletterelement[layer][test][default]{NEW LAYER}
\setupletterlayer[test][alternative=default, x=3cm, y=3cm, state=start]
\startletter
Where is the \quote{NEW LAYER}?
\stopletter
--8<---------------cut here---------------end--------------->8---

TIA for any hints!
