The way to resolve this is to place the generated code into different C++
namespaces. For example, if you have a.xsd and b.xsd with identically-
named types then you can compile them like so:

xsd cxx-tree --namespace-map =foo a.xsd
xsd cxx-tree --namespace-map =bar b.xsd

This will result in the generated C++ code for a.xsd being placed into the
foo C++ namespace and for b.xsd -- into bar. If your schemas specify target
namespaces, then you will need to add that to the --namespace-map option,
for example:

xsd cxx-tree --namespace-map http://www.example.com/a=foo a.xsd

For more information on the --namespace-map option see the XSD Compiler
