I am glad you managed to answer your own question. You probably
would want to omit specifying the schema (the last line) since
the schemaLocation declaration only makes sense in the root
element. Instead you may want to add the needed attributes to
the root element (see below).

Note that the resulting XML won't be valid with regards to XML
namespaces because you haven't provided the mapping for prefix
'lib:' in the root element. You can fix this by replacing the
code above with something like this:

ofs << "<?xml version=\"1.0\" encoding=\"UTF-8\"?>" << endl
    << "<lib:catalog xmlns:lib=\"http://www.codesynthesis.com/library\">"
    << endl;


If you also want to specify the schema location then it becomes:


ofs << "<?xml version=\"1.0\" encoding=\"UTF-8\"?>" << endl
    << "<lib:catalog xmlns:lib=\"http://www.codesynthesis.com/library\"" << endl
    << "  xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\"" << endl
    << "  xsi:schemaLocation=\"http://www.codesynthesis.com/library "
    << "library.xsd\">" << endl;


With namespaces streaming becomes a bit tricky.
