Please note that when two or more concepts are used to replace a focus concept slot in an expression template, a plus sign (‘+’
) must be added between them to ensure the resulting expression is syntactically valid.
...
When a cardinality constraint is not provided in an information slot preceding a focus concept, relationship group or attribute name-value pair, the default cardinality that is assumed is [[1is 1..*]]. This means that by default focus concepts, relationship groups and attribute name-value pairs must appear at least once in the resulting expression, but may also be repeated many times. The SNOMED CT concept model, if enforced, may also impose some additional cardinality constraints on the number of times an attribute may be repeated. However, these additional concept model rules are not directly implied by the expression template itself.

The above expression template is therefore equivalent to the following template, in which the cardinality of [[ 1..*]] is is explicitly stated on the focus concept, the relationship group, and each attribute name-value pair.

Please note that if the international SNOMED CT concept model was enforced, the above expression would not be valid due to the
appearing twice in the one relationship group.
