Given any EObject "x" contained by a resource, (that includes any
XSDConcreteComponent), you can save it back to it's original location like
this
Resource resource = x.eResource();
resource.save(null);
or you can save it to a stream like this
resource.save(System.out, null);
If you want to save your whole set of related schemas to a new location, you
can call resource.setURI() for each resource to change it's location. You'll
also need to change the import/includes to use the new names.
You can only merge included schemas into a single schema since imports imply a
different namespace and each different target namespace will require a
different schema document to be defined. If you want something to be
contained by a particular schema you would add it to the list returned by
xsdSchema.getContents(); adding it to a new container will remove it from its
old container automatically.
