Documentation Breakage at 2.5.6

Hi All,

I'm trying to upgrade the NonStop port from 2.3.7 upward eventually to 2.15.1 and hit a snag on documentation. The xmlto component is a bit new to me and I hit the following error:

    XMLTO git-remote-testgit.1
xmlto: /home/git/git/Documentation/git-remote-testgit.xml does not validate
(status 3)
xmlto: Fix document syntax or use --skip-validation option

The -skip-validation option just takes me to a different problem validating via sourceforge URL that appears not to exist anymore, although I had to modify ./git/Documention/Makefile, which is vexing.

    XMLTO git-remote-testgit.1

Makefile:328: recipe for target 'git-remote-testgit.1' failed

Any advice on getting past this? It would be nice to get git help to working again. An answer of "you need to get past 2.5.6" is ok too as long as I know where I'm going.

Thanks, Randall
