Now compare the 2 DTDs (your original XML or SGML and the generated). If something is missing in the generated one, fix the original DTD, then redo STEP 6, else you will get out of sync. Note that the exported DTD is SGML (unless there is a parameter in the SGML declaration I did not find) . Therefore compare taking into account this difference. Also, all entities you used will be expanded. e.g. you get this sort of thing:
<!ELEMENT Step - - (Title, Goal?, Prereq?, ((Para | List | Listing)* | Substep)*, Comments?) ><!ATTLIST Step Id ID #IMPLIED ><!ELEMENT Para - - ((#PCDATA | A | Strong | Emph | Code)*) >
