+%     In the current implementation, the version of \cs{framebox} here
+%     handles horizontal placement differently from the \LaTeXe{} one.
+%     In the latter, the \meta{content} is placed allowing horizontal space for
+%     the separation but \emph{not} the rules. That can lead to overlap when
+%     there is no separation distance. Vertically, both implementations use
+%     the same approach, and there is no chance of overlap. This aspect is
+%     for \emph{discussion}.
