\ConfigureListOf{description}%
                {\HCode{<DL>}}
                {\HCode{</DL>}}
                {\HCode{<DT>}\bgroup \bf}
                {\egroup\HCode{<DD>}}       

the `itemize' environment carries the default setting of

             \ConfigureListOf{itemize}
                {\HCode{<UL>}}
                {\HCode{</UL>}}
                {\DeleteMark}
                {\HCode{<LI>}}            

and the `enumerate' environment carries the setting of

             \ConfigureListOf{enumerate}
                {\HCode{<OL \OLStyle>}}
                {\HCode{</OL>}}
                {\DeleteMark}
                {\HCode{<LI>}\AnchorLabel}  

The \OLStyle command asks for the html OL list to carry labels consistent with those given in the default setting of LaTeX, the \DeleteMark command asks that the label created by LaTeX will not be included in the html file (to be replaced by <LI>), and the \AnchorLabel command asks for anchors to be assigned to the automatically generated labels of LaTeX (accessed with the \label and \ref commands).
