I could be having an epiphany or I could just be rather dumb … but here goes. The paper you referred us to Tom has all the attributes [general usage] of the mDL but a totally different purpose. Could we / should we therefore take a broader perspective on 18013-5 and rather than focus on the mDL per se (though it is a good subject for thinking around) think more of a Personal Identification Digital Document (PIDD) or potentially (though privacy risks abound) a PIDD ‘Store’, i.e. the common PII with other meta-data specific to a particular use, e.g. mDL, Cert of Vaccination … or of any other worthy attribute? There is nothing about an mDL which is so special, is there? I get the point that as a focus for a specific instantiation it is valuable, but a slant in one’s perspective opens up the basic tool for many parallel purposes, as the referenced paper suggests. Does this make any sense? Richard G.
