These are documents 3 and 4 of a set of 3 :). The documents are: - bundles - a reusable block of DFDL statements - Conversions - a proposal for the semantic details as to how conversions are chosen during the operation of a DFDL parser. These semantics include a description as to how the conversions can be extended. These documents round off the current set of proposals from the extensibility design team. The team has reasonable consensus on these documents, with the (relatively trivial) exception of bundles where there may be some outstanding issues. We believe that with these two documents there is enough material to support the necessary extensibility. However, we have not yet worked through enough examples of round tripping to understand whether that is sufficiently well covered and we are expecting that all the ideas in these documents will require refining by the group as a whole. I would like to discuss these two documents on Wednesday (if possible). Thanks, Martin
