When you use three arguments the first is used for the position of text, 
i.e. above the text, margin or edge areas.

Only six or seven arguments work in this case but this only useful in a

You need a new command for this because adding an assignment option can 
produce unexpected results, e.g. the example below won't work anymore.

\setupheadertexts[{\date[d=...,m=...,y=...]}]
