Another PRD2 build

Hello UBL TC,

I've uploaded another test build of PRD2 to the OASIS site:

   http://www.oasis-open.org/committees/download.php/19316/prd2-UBL-2.0-test.zip

This includes the fix to the Linux validation problem and also a
generated PDF file to satisfy the letter of the OASIS process.  I
*think* that this version is editorially good to go Friday.
