[NTG-context] description setup error

[Meer, H. van der]

Of all the parameter values for \setupdescriptions[][alternative=value] there is one that fails here, i.e. "right". right is a value mentioned in http://wiki.contextgarden.net/Command/setupdescriptions.

Below a minimal example and the error.

\definedescription[htmldd][before=,after=]
\setupdescriptions[htmldd][alternative=right]
\starttext
Text before.\crlf
\starthtmldd{item-1}description\stophtmldd
\starthtmldd{item-2}description\stophtmldd
Text after.
\stoptext

! Undefined control sequence.
