[Oreka-devel] DOMWriter.hpp is missing from xercesc-3.1.3

Hello!
I am installing Oreka on 64-bit CentOS 6.2. I am building this from source as instructed on http://oreka.sourceforge.net/oreka-documentation.html#building-oreka
While installing dependencies, I found that xercesc-2.8.0 is discontinued. So I installed xercesc-3.1.3.
Now the issue is that xercesc-3.1.3 does not have DOMWriter.hpp and DOMWriterFilter.hpp.
WHEREAS oreka source code refers to both of these files. I am unable to build orkbasecxx because of this.
Please suggest how to proceed.
Thank you!
