[NTG-context] how to get a commalist out of {}-brackets

[Peter Schorsch]

Hi,

I need to forward an embedded commalist to an subfunction. The problem: how
can I get rid of the {}-brackets to access the embedded commalist?

The functions looks like:

\def\function#1[#2]
{\getparameters[label][a=,b=,embedded=,#2]
 subfunction[\labelembedded]
...}

\def\subfunction#1[#2]
{\getparamters[label][a,c,#1]
 \labela        % will answer with emptyness
 #2             % returns {a=,c=} ... but I need for the getparamteres a=,c=
...}

to call the function:

\function[a=etwas,b=ddd,embedded={a=nochWas,c=hope}]
