Yes, you can parse/serialize XML fragments that correspond to individual
schema types. For that, however, you will need to set up the XML-to-DOM
(for parsing) and DOM-to-XML (for serialization) stages yourself. Then
you can instantiate an object model type from DOMElement or DOMAttr
as well as serialize an instance of an object model type to DOMElement
or DOMAttr.

For more details on how to implement this kind of parsing, see Q 2.4 and
2.5 in the C++/Tree Mapping FAQ[1] as well as the multiroot example in
examples/cxx/tree/.

For serialization, see Q 3.1 and 3.2 in the FAQ[1]. Once you have an
object model node and DOMElement, you can perform serialization by
using the serialization operator:

const SomeType& x = ... // Object model instance to serialize.
DOMElement& e = ... // DOM element to serialize to.

e << x;
