There is a separate entry for notes in recspec ("WD-NOTE") (hopefully that works, but maybe it does not, in which case we should talk to Robin:-)

After all, these are URI-s, even if in an abbreviated form, whereas the diagram does not really make that clear… It is also more in line with the Turtle/Prov-n codes.

It is only way later (in section 3.8) that I realized that the slot is used for a time value and '-', I presume, means 'not specified'. Maybe it is worth putting some sort of a forward reference into 3.3. to help the poor reader…

After all, ex:chart2 is created exactly through the same steps as ex:chart1 (illustrate-composition-compose-data) except that using a different data set, and that does not show at all.
