DMN17 — Clarification on the FEEL sort function with the precedes function

In section 10.3.4.9 of the DMN 1.5 specification (page 153, PDF 161) the sort function is defined with the possibility to use a precedes boolean function to compare list elements.

Text should be added after table 80 to clarify how the precedes function deal with equal parameters.

I would propose that precedes return false when both parameters are equals.

This new paragraph should also establish the stability expectation of the sort FEEL function (equal elements keep the order of the original list).

I would propose that the FEEL sort function does not guarantee stability. Guaranteeing stability could impact certain sort performances.
