In every element, cluster, slot and others in Archetype Editor there is Occurences attribute.
For my Element at0005 I set this attribute to 0..\*
How will it be represented in instance of this archetype?
Blah-blah-1 Blah-blah-2 Value1 ... Blah-blah-2 Value2 ...
The same question is about clusters.

If you mean, what does is mean for data instances… ‘occurrences’ means that the pattern defined in this part of the archetype, e.g. some ELEMENT at0004 (e.g. meaning = ‘systolic pressure’) can repeat N times in the data. This makes sense for nodes like Location in openEHR-EHR-EVALUATION.problem-diagnosis.v1 and many other nodes.
does this answer the question?
