Project overview

Currently EclipseLink OXM does not support the unmarshalling of documents that contain top-level elements that represent simple types. For example, the JAXB TCK uses the following types of test documents:

XML Schema:

<schema ...>
...
   <element name="NISTSchema-base64Binary-enumeration" type="nist:NISTSchema-base64Binary-enumeration-Type"/>
 
   <simpleType name="NISTSchema-base64Binary-enumeration-Type">
      <restriction base="base64Binary">
         <enumeration value="bHlsY2JmaXFjaW9ubmg="/>
      </restriction>
   </simpleType>
</schema>

XML Instance Document:

<NISTSchema-base64Binary-enumeration
    xmlns="NISTSchema-base64Binary-enumeration-NS"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="NISTSchema-base64Binary-enumeration-NS enumeration.xsd">zGk=</NISTSchema-base64Binary-enumeration>

Goals:

• Allow the user to marshal and unmarshal XML documents that contain simple type root elements.
