In my case, all I get is
Chunking isn't supported with libxslt
message, and no output, but I guess this is configuration problem on my side.

I certainly miss something. There's code from boostbook.jam:
manifest = HTML.manifest ;
local target = [ generators.construct $(self.project) $(manifest)
: $(type) : $(property-set) : $(base-target) ] ;
You ask to create a target called HTML.manifest, and get it.

LOCATE on $(target) = $(dirname) ;
This line changes LOCATE setting on the manifest file, as I understand it. If
I comment out this line, the disappeared part goes back (but "html" part
Your comment is right. The thing you do with LOCATE/MkDir are bypassing
builtin V2 mechnisms. More comments later.

I have no idea -- we are not prepared that one action
creates unknown number of targets. Need some design.

Well, the way you've described it really looks not very nice. However, I see
quite clear approach in the implementation. We can't handle directories
directly. So, insread of generating directory from the docbook source, you
generate manifest file. The action which generates manifest file, also creates
a buch on html files.
What's not nice currently, is relocating of manifest file. We've two
1. Don't do anything. The manifest file will be generated to
"bin/gcc/debug/HTML.manifest". The xsl-dir rule will find out the location
of manifest file and store generated files in the same location. That's as
clean as possible. Of course, the path "bin/gcc/debug"... is wierd. But this
should be fixed.
2. Change manifest location in another way. The 'virtual-target' class has
'set-path' method. This will eliminate the need for 'common.MkDir' call.
It's still not quite clean, but will avoid deep directories right now.
> Still no clue how to handle catalogs, unfortunately :(
Frankly, I don't know how they should work. I'd imagine that
some Jamfile has
xml-catalog boostbook : "http://nowhere.com"="/home/ghost/dtd/nowhere" ;
And that there's <xml-catalog> feature, which is honored by xslt actions. On
the other hand, you was trying to make the docbook rule to automatically
create a new target locally. I don't know what is better.
