  The open issues in the development of models for the breakup of exotic nuclei
and the link with the extraction of structure information from experimental
data are reviewed. The question of the improvement of the description of exotic
nuclei within reaction models is approached in the perspective of previous
analyses of the sensitivity of these models to that description. Future
developments of reaction models are suggested, such as the inclusion of various
channels within one model. The search for new reaction observables that can
emphasise more details of exotic nuclear structure is also proposed.
