(I don't see a place on wikimatrix to update information about WikiFeatures, report bugs, etc...)

Anyway, I noticed the JSPWiki syntax has headings "upside down" ( see http://www.wikimatrix.org/show/JSPWiki )

the comparison matrix shows JSPWiki syntax as:

! Level 1
!! Level 2
!!! Level 3


and, it is more accurately,

!!! biggest (h2)
!! smaller (h3)
! smallest (h4)

I don't know if "!!!" is always h2, or if it depends on the template used.  But it seems !!! is the "biggest" heading, and "!" is the smallest (ie, you can't use all html headings, h1 through h6).

thx,
