[NTG-context] Request for delimited texts

Hi all, is it possible to extend the delimited texts implementation in such a way that the environment would accept optional arguments. What I have in mind is something like this: \setupdelimitedtext [quotation] [% author=Default Author, right=”\wordright{\delimitedtextparameter{author}}] \starttext \showframe \startquotation% [author=Some Author] \dorecurse{50}{text } \stopquotation \startquotation% [author=Another Author] \dorecurse{50}{text } \stopquotation \stoptext Greeting Andreas
