Oh, sorry. I have indeed used the wrong alias in the example. I intended
to write
SELECT a/data[at0001]/items[at0004]/value
FROM EHR e CONTAINS COMPOSITION a[openEHR-EHR-COMPOSITION.encounter.v1]
WHERE a/data[at0001]/items[at0004]/value/value >= 140
What ensures that the identified path in the SELECT section references
the same data instances that are contrained with the same identified
path in the WHERE section ?
Greetings
Georg
