There is no support for an automatically generated Index in the
print stylesheet.  (bin/collateindex.pl provides support for the
HTML stylesheet.)

Using Equations w/o titles results in incorrectly numbered
  equations with titles.  Use InformalEquation instead.

InlineEquations don't work in the RTF backend.  It's not my fault.

Callout support is somewhat fragile.

Line numbering of linespecific displays is somewhat fragile.

In two-sided mode, with the RTF backend, the appropriate
  alternation of inner/outer headers and footers does not work
  correctly unless %page-number-restart% is true.  This is
  caused by a limitation in RTF.

CHAR alignment in tables is not supported
