We all know that mediawiki does not support eqref.
We have to think about a solution for the imported documents. Right now they are transformed into links to the page the equation is into, but i do not think that this solution is the best one ever, since it gives false sense of having solved the problem.
I would rather insert, alongside with the link to the page the equation is into, a text note that makes clear that there was a eqref, otherwise the text becomes unreadable.
I am thinking about something like
We have now almost proved the theorem, for we have the expansion
\eqref{e37.10.11.16} for $z\in A'$ and we have formulae for the
coefficients. Note that in fact the coefficients given in
\eqref{e38.10.11.16} agree with the formula \eqref{e33.10.11.16} by Cauchy's
Theorem.transformed into
