Hi,

I have two enumerations:

\defineenumeration
   [exercici]
   [alternative=serried,text={\startcolor[middlecyan]Exercici\stopcolor},stopper={.\space},left={\bgroup},right={\egroup},width=fit,headstyle=\ss]

\defineenumeration
   [exercicivora]
   [alternative=serried,text={\startcolor[middlecyan]Exercici\stopcolor},stopper={.\space},left={\bgroup\startframedtext[background=screen,frame=off,width=broad]},right={\stopframedtext\egroup},width=fit,headstyle=\ss]



I just want to join into one: when I do \startexercici ... \stopexercici 
ConTeXt do the first, and when I pass \startexercici[vora] ... 
\stopexercici then do the second. That is, 'vora' as optional argument.

How can I achieve that?

I use MKIV.

Thanks in advance,
Xan.
