Creation of PAR files - 2A10 (RosettaNet)

Using DTD and the PIP tools, when we try creating the PAR files for 2A10, following error appears

<< …
Got Error:class Message= …/RNTD/rntd.dtd (No such file or
… >>

Our guess for the error is that since the DTD files has a lot of recursive references. Has anybody come across such cases. Please help

Problem solved. This problem occurred because the PAR file was for 4.6 version. There is a SR in the advantage site that details out the solution.
