You have not told us what version of Cocoon you use.
Looking at the following URL, i guess 2.0 ... is that correct?

You do not need to set the "catalog-class-name".

Are you seeing messages from the entity resolver when
Cocoon starts and for each file that it processes?
If not, then your configuration is not correct.

However, the entity resolver is only providing access
to local copies of the DTDs. As long as you have network
access, then Cocoon should just get the remote copy of
the DTD from the network URL. Slow of course.

Does your DTD refer to other DocBook DTDs?

What do you expect to see? The Sitemap that you have
provided does not handle that, but perhaps you just
provided us a tiny snippet of your sitemap.

I suggest that you start with normal DocBook files
(without any SVG) to get that working first.

Sorry, i do not know anything about SVG embedded in DocBook.
I wonder if you need to get Cocoon to dissect the source file,
generate and serialise the SVG parts, then aggregate it again.
