I used dox because I needed a macro to describe options. But now I see that I can say \NewDocElement{Option}{option}, which is fine. Something similar affects the colordoc package because it redefines doc's \macro@finish, which has been changed. What should we do? Will the LaTeX3 team contact the authors of these packages or should rather I do it myself? > Thanks for trying latex-dev. It helps to identify such problems :-) You are very welcome :) Robert > Ulrike
