PPMN — At line 1015, sentence starting wtih "Additonally, ..." wording is incorrect.

There are several issues with line 1015 sentence starting with: "Additionally, ...": the word "contain" (spelled "conain" in the doc) is used to mean composition, the attribute "parts" is used (no need to make part plural, it is already a collection), and finally it mentions an EntityComposition relationship which does not exist.
