@RalphTro Interesting question that came up during testing:

Do we normalise values only from standard fields or also form user extension fields?

In examples/SensorDataExamples.xml there is a <example:machine>urn:epc:id:giai:4012345.ABC</example:machine>. Should normalise this value to https://id.gs1.org/8004/4012345ABC? I vote yes. ;)

Good catch, @Echsecutor ! I tend to agree with you. This way, it's more unambiguous.
