Re my answer below...

Even better than that:  SCHEMA 1 (Untitled8.xsd):

<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"
xmlns:in="http://www.w3.org/2001/XMLSchema"
elementFormDefault="qualified" targetNamespace="http://Untitled8">
    <xs:import namespace="http://Untitled9/in"
schemaLocation="untitled9.xsd"></xs:import>
    <xs:element name="base">
        <xs:complexType>
            <xs:sequence>
                <in:element name="base">
                <in:complexType>
      <in:attribute name="myNodeABC" type="in:string"/>
      <in:attribute name="myNodeXYZ" type="in:string"/>
    </in:complexType></in:element>
            </xs:sequence>
            <xs:attribute name="myNodeABC"></xs:attribute>
            <xs:attribute name="myNodeDEF"></xs:attribute>
        </xs:complexType>
    </xs:element>
</xs:schema>


SCHEMA 2 (Untitled9.xsd):

<?xml version="1.0" encoding="UTF-8"?>
<in:schema xmlns:in="http://www.w3.org/2001/XMLSchema"
    targetNamespace="http://Untitled9/in"
elementFormDefault="qualified">
    <in:element name="base">
    <in:complexType>
      <in:attribute name="myNodeABC" type="in:string"/>
      <in:attribute name="myNodeXYZ" type="in:string"/>
    </in:complexType>
  </in:element>
</in:schema>

Resulting XML doc:

<?xml version="1.0" encoding="UTF-8"?>
<base xmlns="http://Untitled8"
     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
     xsi:schemaLocation="http://Untitled8
file:/C:/Documents%20and%20Settings/Ingrid/Desktop/Untitled8.xsd"
myNodeABC="" myNodeDEF="">
    <base myNodeABC="" myNodeXYZ="">SCHEMA 2 content </base>
</base>

So the solution below is probably not strictly speaking the correct
way...
