% The following code creates another command \@indexlabel, which,
% along with Hevea's \@currentlabel serves to store the current values
% of counters. However, \@currentlabel keeps the value of counters
% incremented by \refstepcounter (see the definition of
% \refstepcounter in latexcommon.hva), which includes chapter and
% section counters, as well as theorems, \items, etc. On the other
% hand, \@indexlabel keeps only the values of sectioning counters.
% This is done by redefining the sectioning commands.
