\begin{document}

\deleted[id=jv]{This is an irrelevant statement.} This is \replaced[id=dm]{a correct}{an erroneous} statement. \added[id=jv, comment={I think it is correct, but check.}]{This is a new statement.}

This is a discussion-triggering statement. \comment[id=dm]{Is it really?} This is a yet another particularly \highlight[id=dm, comment=Is that the right word to use?]{discussion-triggering} statement.
