Ok, I undestand. I apologise that my example was too short. I'd like to have things more flexible: If an arbitrary and irregular number of levels is introduced (sections, subsections, etc., numbered hierarchically as usual), the topic numbering should remain continuous and unaffected (that's why I thought, a separate definition, as in \definehead[topic][...], would be appropriate). Conceptually, though, "topic" is a section-like subdivision, so, for example, should appear in the TOC. This is typical e.g. in (German) law texts (here with "§" as a topic marker but this is not the point), Example: I. ... "Chapter" § 1 ... 1 ... "Section" § 2 ... Topic in section 1.1 ... "Subsection" § 3 ... Topic in subsection § 4 ... 1.2 ... § 5 ... 2 ... § 6 ... § 7 ... 2.1 ... § 8 ... II. ... § 9 ... Topic in chapter 1 ... § 10 ... § 11 ... 1.1 ... § 12 ... Of course, referencing, entry in TOC, index etc. should be correct. It would be even more preferable if one could "attach" the topic numbering to a specified level, say, chapters. The above example then would become: I. ... "Chapter" § 1 ... Topic in chapter 1 ... "Section" § 2 ... Topic in section 1.1 ... "Subsection" § 3 ... Topic in subsection § 4 ... 1.2 ... § 5 ... 2 ... § 6 ... § 7 ... 2.1 ... § 8 ... II. ... § 1 ... First topic in second chapter 1 ... § 2 § 3 1.1 ... § 4 ... Thank you & sorry for the incomplete first question! Ulf
