Present Martin Westhead Bob McGrath Mike Beckerle Geoff Judd Jim Myers Suman Kali F2F Agenda DFDL underlying mechanisms Conversions/context/hidden elements - Relationship to variables Scoping document Choices and wildcards Null and default values Actions to lead to a final document set. - What APIs to we expect DFDL implementations to provide to users - Which XML Schema constructs are supported - The set of DFDL properties we provide - Review of trackers Conversions discussion It was proposed that the document is split to try to separate those aspects of the document which are clearly "extensions" from those which are defining underlying semantics. There is clearly a need to provide one or more detailed worked examples which go through all the operations of conversion choice and context. (Martin will undertake to try to do at least one for next week, Bob has also volunteered to contribute material here)
