You cannot really add it unless there is a slot in c_type (e.g.,
element or attribute) for it. One way to create such a slot is to
modify your hello.xsd schema:

<?xml version="1.0"?>
<xsd:schema
       targetNamespace="abc"
       xmlns="abc"
       xmlns:xyz="xyz"
       xmlns:xsd="http://www.w3.org/2001/XMLSchema"
       elementFormDefault="qualified">

        <xsd:import namespace="xyz" schemaLocation="embed.xsd"/>

        ...

	<xsd:complexType name="c_type" mixed="true">
		<xsd:sequence>
                        <xsd:any namespace="##other" processContents="skip" minOccurs="0"/>
                        <xsd:element name="embed" type="xyz:embed_type" minOccurs="0"/>
		</xsd:sequence>
	</xsd:complexType>

        ...

</xsd:schema>


You can modify the schema only for code generation and use the original
schema for validation. With c_type generated from the schema above, you
can rewrite you code like this:

DOMNode * embed = c_n._node()->getFirstChild();
xyz::embed_type e_n (static_cast<DOMElement*> (embed), 0, 0);
c_n.embed (e_n);

Also note that you will need to reset the embed element before serialization
if you don't want it to be written out:

c_n.embed ().reset ();
