We did not know that null was a possible value for some of these
xmlAddDocEntity() parameters. The libxml documentation is not clear
about this.

We will have to add some method overloads in libxml++ 2.11/12. It's too
late to add them to libxml++ 2.10 now.

In the meantime, you should be able to call cobj() and use the
xmlAddDocEntity() function directly.
