NIPWG10 raised the point that the S-100 ECDIS may receive multiple S-128 datasets from different providers, with potentially overlapping contents. Appendix C-3 should be updated to explain to implementers how such conflicts can be resolved. Specifically
multiple S-128 datasets are allowed
Information from multiple S-128 datasets should be merged on the ECDIS
When merging, the most recent dates are preserved. So, if a dataset is included in >1 S-128 list, the most recent date is normative and should be used to generate the Update Status Report.

S-164 will contain tests of this functionality.
