In PPs and PP-Modules, the default text bullet for refinement states the following:
"Refinement operation (denoted by bold text or strikethrough text): Is used to add details to a requirement (including replacing an assignment with a more restrictive selection) or to remove part of the requirement that is made irrelevant through the completion of another operation, and thus further restricts a requirement."
The parenthetical can be removed as the act of replacing an assignment with a selection is now considered to be (partially) completing the assignment rather than refining it. The use of bold text in that specific situation just created unnecessary confusion for the reader.
