Hi all, I'm reading through the AQL specs, on this section http://openehr.org/releases/QUERY/latest/docs/AQL/AQL.html#_containment it is mentioned that CONTAINS is from parent to child.
Most examples there show COMPOSITION CONTAINS ENTRY. In a case that there is a SECTION in the middle, should AQL be always COMPOSITION CONTAINS SECTION CONTAINS ENTRY? Before reading this specific point I was thinking that CONTAINS allowed to look anywhere on the COMPOSITION tree, semantically looking for "child or descendant", instead of just "child". If we have only direct "child" references, having a small tree of SECTIONs can make queries more complex, like COMPOSITION CONTAINS SECTION CONTAINS SECTION CONTAINS SECTION CONTAINS ENTRY ... Would it be useful to have that kind of "child or descendant" containment operator added to AQL? What do others think? -- Ing.
