+%D This is a rather old mechanism that we once needed in an actually nice
+%D design. Those were the times that processing a rather complex xml file
+%D with pdftex into a 400 page document took 45 minutes (a few runs) while
+%D nowadays with luatex and mkiv we express runtime in seconds.
+%D
+%D The logic is mostly the same but some work is delegated to Lua so that
+%D we save memory and also run faster. As this was not really a used module
+%D the interface also was upgraded. As we know the bottlenecks in mp we also
+%D work around it a bit.
