DMNFTF — Figure 2 is misleading

The figure shows 3 levels:
1. DRD
2. boxed expressions
3. FEEL

and groups 1&2 as notation.

The problem is, FEEL is both notation and semantics.

The figure shows the FEEL semantic function, and thus is highlighting the semantic aspect of FEEL. The fact that the cells in the boxed expressions contain FEEL syntax is not highlighted.

The figure could be improved in one of 2 ways:
1. rename the callout from 'Expression Language (FEEL)' to 'Execution Semantics'. This more accurately describes the FEEL(...) in the dotted ovals, or
2. delete the FEEL(...) in the dotted ovals. Instead, callout some FEEL expressions from above, e.g., Application.Date - Application . Applicant Date of Birth, not(UK), <18, etc.

Implement improvement 2 from the description.

Also, there is a problem in the boxed invocation. The cell with

Application.Date - Application.Applicant Date of birth

does not result in a numeric age (it results in a days and time duration).
