In the KOMAscript classes, there is also a section type "\minisec" which can
be used below all section headings.
Unfortunately TMX does not seem to recognize it as a header and does not
incorporate it in the structure view nor does it let it fold automatically.
Could you please add minisec to the structure and make them "collapsible"?
The problem is: which hierarchy level do they belong to - I'd place them on
the same level as paragraphs, but I'm not sure how others use them.
