Hello all, In Montréal we talked about the "val/" directory and the annex on two-phase validation being updated for UBL 2.1 but essentially identical to UBL 2.0 (except for some filenames). In other correspondence today I cited how we now have two processing models being discussed for UBL: (1) - for homogeneous deployments of UBL where all instances are at the same specification level, e.g. all are UBL 2.0 or all are UBL 2.1 - the documented two-phase validation process as illustrated in the "val/" directory is suitable (2) - for heterogeneous deployments of UBL, e.g. where UBL 2.0 and UBL 2.1 instances are being used but a particular deployment is stuck on UBL 2.0 until they migrate their system to UBL 2.1 (or any forward-compatible requirement) - the simple two-phase validation process is not suitable - the augmented process in section "4 Validation" of the public review draft is better suited That brought to mind some unfinished business regarding documentation and packaging for UBL 2.1. Do we need to cite Section 4 of the UBL 2.0 customization guidelines in the UBL 2.1 hub document? The same augmented processing model will be important to implementers of UBL 2.1 who need to be forward compatible with future UBL 2.x deployments. Or perhaps more importantly for UBL 2.0 users who need to accommodate 2.1 instances before they can migrate their systems to support UBL 2.1 instances. The existing UBL 2.0 documented processing model cannot accommodate this, while the processing model in the customization guidelines can accommodate this. Do we need a second batch file in the "val/" directory that illustrates this augmented process? I don't think we can because it needs resources that are not committee resources (the instance filters). Crane has the freely-available instance filter resources for implementers to use, but the BSD license I've chosen obliges the source of the materials to be acknowledged (which perhaps isn't appropriate in an OASIS specification). But at the least I think we need to cite the Customization Guidelines from the hub document in the discussion of validation. . . . . . . . . . . . . . .
