Hi Jeni,

You're completely right -- in case we have to guess what the structure
of the source xml document is, it is not possible to state that a
particular transformation is the solution to the problem -- the problem
is not specified precisely.

In particular, I thought that nested a's will always be children of a
span.

I think that precisely defining the structure of the input is more than
halfway progress towards a solution.

Cheers,
Dimitre.
