Using ConTeXt I am trying to produce a nested enumeration like the one below:

```
1  Level 1
   1.1 Level 2
       1.1.1 Level 3
             a) Level 3 subitem
             b) Level 3 subitem

```

I have the following:

```
\defineitemgroup[legal]
\setuplegal[each][n,repeat,joinedup][stopper=]

\setuplegal[1][width=1em]
\setuplegal[2][width=2em]
\setuplegal[3][width=3em]

\starttext

\startlegal
  \item Level 1
  \startlegal
    \item Level 2
    \startlegal
      \item Level 3
      \startitemize[a,joinedup][stopper=)]
        \item Level 3 subitem
        \item Level 3 subitem
      \stopitemize
    \stoplegal
  \stoplegal
\stoplegal

\stoptext

```

However, this produces:

Is there any way to configure the legal itemisation so that enumerations of other types (e.g. alphabetic or Roman) are not affected? Not sure whether this is relevant, but enumerations of other types can appear at any level, not just the 3rd level as shown above.
