There is a translation step for the keywords. For example, if a user
would say \ShowLayout[command=\xxx], you would have to retrieve it as
\getvalue{ShowLayoutcommando} (note the Dutch translation
commando). Translation is done for all keywords that are used in
Context's core; language variants are mapped to a canonical value,
often but not always the Dutch form of the keyword. I do not remember
where to look this up; usually I just look into the trace log to find
out.
