Hello Matti,

You could map this as follows.  I believe you were just missing the 
"/text()" at the end of your XPath statements on your choice mappings.

import org.eclipse.persistence.oxm.NamespaceResolver;
import org.eclipse.persistence.oxm.XMLDescriptor;
import org.eclipse.persistence.oxm.mappings.XMLChoiceObjectMapping;
import org.eclipse.persistence.sessions.Project;

public class DesignationRequestProject extends Project {

   public DesignationRequestProject() {
       this.addDescriptor(getDesignationRequestDescriptor());
   }
   
   private XMLDescriptor getDesignationRequestDescriptor() {
       XMLDescriptor xmlDescriptor = new XMLDescriptor();
       xmlDescriptor.setJavaClass(DesignationRequest.class);
       xmlDescriptor.setDefaultRootElement("app:DesignationRequest");
       
       NamespaceResolver namespaceResolver = new NamespaceResolver();
       namespaceResolver.put("app", "urn:your-namespace");
       xmlDescriptor.setNamespaceResolver(namespaceResolver);
       
       XMLChoiceObjectMapping numericIdMapping = new 
XMLChoiceObjectMapping();
       numericIdMapping.setAttributeName("numericId");
       numericIdMapping.addChoiceElement("app:numericId/value/text()", 
String.class);
       
numericIdMapping.addChoiceElement("app:numericIdTypeB/value/text()", 
String.class);
       xmlDescriptor.addMapping(numericIdMapping);
       
       XMLChoiceObjectMapping alphanumericIdMapping = new 
XMLChoiceObjectMapping();
       alphanumericIdMapping.setAttributeName("alphanumericId");
       
alphanumericIdMapping.addChoiceElement("app:alphanumericId/value/text()", 
String.class);
       
alphanumericIdMapping.addChoiceElement("app:alphanumericIdTypeB/value/text()", 
String.class);
       xmlDescriptor.addMapping(alphanumericIdMapping);
       
       return xmlDescriptor;
   }
   
}


For your XML schema to get the namespace qualification from your examples 
you could use something like the one below.  Note you will need to use 
elementFormDefault="unqualified" and make all elements that will be 
namespace qualified global elements.

<xs:schema 
   xmlns:xs="http://www.w3.org/2001/XMLSchema"; 
   elementFormDefault="unqualified" 
   attributeFormDefault="unqualified" 
   targetNamespace="urn:your-namespace" xmlns="urn:your-namespace">
   <xs:element name="DesignationRequest">
       <xs:complexType>
           <xs:choice>
               <xs:element ref="numericId"/>
               <xs:element ref="numericIdTypeB"/>
               <xs:element ref="alphanumericId"/>
               <xs:element ref="alphanumericIdTypeB"/>
           </xs:choice>
       </xs:complexType>
   </xs:element>
   <xs:element name="numericId" type="value"/>
   <xs:element name="numericIdTypeB" type="value"/>
   <xs:element name="alphanumericId" type="value"/>
   <xs:element name="alphanumericIdTypeB" type="value"/>
   <xs:complexType name="value">
       <xs:sequence>
           <xs:element name="value" type="xs:string"/>
       </xs:sequence>
   </xs:complexType>
</xs:schema>
