Error parsing a DTD using lxml?

I took a look at the nitf-3-4. Dtd and found that it references an external module xhtml-ruby-1. Mod which can be downloaded at this link .

This needs to be present in the current directory so the DTD parser can load it.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
