<!--l. 1960--><p class="noindent">
</p><ol type="a" >
<li>Broken math formulas, such as &#8216;<span 
class="cmtt-10">$R=\{x|x$ is real $\}$</span>&#8217; instead of &#8216;<span 
class="cmtt-10">$R=\{x|x \mbox{ is real } \}$</span>&#8217;.
</li>
<li>Math mode employment for presenting nonmath content, such as &#8216;<span 
class="cmtt-10">$$\vbox{...}$$ </span>&#8217; instead of
&#8216;<span 
class="cmtt-10">\begin{center}\vbox{...}\end{center}</span>&#8217;. </li>
<li>Unmatched parentheses within entries of arrays, such as &#8216;<span 
class="cmtt-10">\begin{array}...(... &amp; ...)...\end{array}</span>&#8217; instead
of &#8216;<span 
class="cmtt-10">\begin{array}...\mathrel( ... &amp; ...\mathrel)...\end{array}</span>&#8217;. </li>
<li>Incorrect annotation of delimiters, such as &#8216;<span 
class="cmtt-10">\bigl\{...\bigr|...\bigr\}</span>&#8217; instead of &#8216;<span 
class="cmtt-10">\bigl\{...\bigg|...\bigr</span>&#8217;
</li>
<li>Empty bases for subscripts and superscripts, such as &#8216;<span 
class="cmtt-10">{}^{...}, {}_{...}</span>&#8217; instead of &#8216;<span 
class="cmtt-10">{\csname</span>

<span 
class="cmtt-10">HCode\endcsname{}}^{...}, {\csname HCode\endcsname{}}_{...}</span>&#8217;. </li>
<li>Use of the operators &#8216;<span 
class="cmtt-10">^</span>&#8217; and &#8216;<span 
class="cmtt-10">_</span>&#8217;, instead of &#8216;<span 
class="cmtt-10">\sb</span>&#8217; and &#8216;<span 
class="cmtt-10">\sp</span>&#8217;, outside the presence of TeX4ht. (TeX4ht becomes active
only at the &#8216;<span 
class="cmtt-10">\begin{document}</span>&#8217; command. The &#8216;<span 
class="cmtt-10">early_</span>&#8217; and &#8216;<span 
class="cmtt-10">early^</span>&#8217; options extend this awareness to the
preambles of the source latex documents.)
