While you can use XSD if your target has a fairly complete Linux setup,
XSD/e is normally better suited for mobile/embedded systems. In
particular, the C++/Hybrid mapping in XSD/e is similar to C++/Tree in

Yes, you will need to build Xerces-C++ for this target. Xerces-C++ uses
the standard autotools-based build system and the configure command line
will look along these lines:
./configure --host=<host-triplet> CFLAGS=-O2 CXXFLAGS=-O2 \
Some people run into trouble with building/using Xerces-C++ on stripped-
down embedded Linux systems because some of the dependencies are not
available or are not fully functional. The common example is the iconv
library used for character conversion. But if you have a fairly complete
Linux setup on your target, then this should work without any problems.

The XSD runtime (libxsd) is a header-only library so this step is not

Yes, you will want to compile your schemas on your Windows box since that's
where you will be doing the development. Then you can copy the generated
code to the Ubuntu box for cross-compilation to the target. You could also
compile the schemas on the Ubuntu box.

Yes, this will be the last step.

There is no dedicated guide but the above instructions should generally
be sufficient. If you decide to go with XSD/e, then the whole process
will be much simpler since there are no external dependencies in XSD/e
(e.g., to Xerces-C++). All you will need to do is build the XSD/e
runtime library (libxsde) which is quite easy to do for both VC++
and a cross-compilation target (see the INSTALL file inside the XSD/e
distribution for details).

We don't provide such packages but some distributions might. For example,
Debian has a Xerces-C++ package for their armel target.
