[NTG-context] using \doifmodeelse the right way

[Peter Münster]

Hello,

\externalfigure[prefix-\doifmodeelse{blub}{blub}{notblub}][width=0.5\textwidth]
does not work.

I tried some combination of \expanded, \unexpanded, \expandafter etc but
without success. In the end, I write:
\doifmodeelse{blub}{%
  \externalfigure[prefix-blub][width=0.5\textwidth]}{%
  \externalfigure[prefix-notblub][width=0.5\textwidth]}

Is this the most elegant way, or do you know better?
(I would prefer less redundancy)

Cheers, Peter
