Example 2

Another example of an expression template with multiple cardinality constraints is shown below. This expression template is used to generate expressions that represent a clinical finding with explicit context.

...

The first cardinality constraint (i.e. 1..1 ) indicates that exactly one value should be populated in the Condition slot. The second cardinality constraint (i.e. 1..2 ) indicates that it is valid to include either 1 or 2 relationship groups (named "AFgroup") in the resulting expression. Each AFgroup relationship group must have exactly one
