Present ------- Mike Bekerle Tara Talbott Martin Westhead Geoff Judd Steve Hanson Bob McGrath Reports from Active Trackers ---------------------------- Scoping tracker is being worked on - no news. Extensibility group is moving forward - nothing to report yet Discussion of Geoff's documents ------------------------------- Variables doc Mike observed that variables could be used in place of his extensibility proposal on annotations. Martin asked about whether we wanted to include this in the standard. Is the complexity worth the addition - the feeling of the meeting was probably it was. Martin proposed that instead of binding a variable value to an element, the variable value should be set with an XPath expression. Discussed the question as to whether the variable value can be reset, whether it can/should be scoped in the same way as annotation attributes. Next step will be for Geoff to revise the document to look at cases where value may need to be reset and start to explore some of the semantic issues involved. Choices doc Discriminator type - what if discriminator is not a string? For efficiency can we handle discriminators that are integers? Suggest that instead of discriminators being computed to strings they are computed to an XPath value with its implied type so that numeric discriminators do need to be converted to strings. Wildcard docs Group seemed fairly happy with this proposal as it stands.
Martin, Please can you add a discussion of the semantics of DFDL Variables to the agenda of tomorrow's telecon. I have attached a document with some thoughts that I have had on the subject.
