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

The stylesheets can't automatically put callout marks on a

PROGRAMLISTING or SCREEN if the text comes from an external file

using the LINESPECIFIC INLINEGRAPHIC trick.

"Extra" 
 elements appear in the HTML output if you put block

elements inside of <para> elements in your source. The problem

is that

  <para>Some text ...

Is translated into

  
Some text 
...

but HTML doesn't allow "table" inside a P, so the begin table

implies an "
" which makes the 
 after the table erroneous.

I don't have a good answer for this, but I'm tempted to make all

 tags empty in the HTML so that the browser has to imply all

the 
s.
