Creating epub version of handbooks

[Damjan Marion]

Hi,

I want to create epub version of handbooks. I tried to convert sgml to docbook xml and then apply epub XSLT.

When I try to do "make FORMATS=xml" in handbook directory or use sx/osx i got hundreds of errors  (some of them listed below). 

Am I doing something wrong or xml creation is broken?

Thanks,

Damjan
