-%    The plug definition for now just implements the old interface
-%    currently used by tagpdf. This needs to change and \cs{@mult at ptagging@hook}
-%    replaced by directly using the socket/plug.  
+%    The plug definition for now just uses the definition from
+%    \pkg{tagpdf}. There has to be a decision where such plugs should be
+%    implemented: in the package (like now) then they functions used
+%    from tagpdf should become public, in \pkg{tagpdf}, or in
+%    \texttt{lttagging} in the kernel.
