Support for Root Elements representing Simple Types

ER 217508

Document History

Project overview

This project will add the ability for EclipseLink OX to unmarshal XML documents that have simple types as their root element. Instead of a "rich" top-level element representing a domain object (e.g. Employee, PurchaseOrder), the root element may be a simple primitive value.

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 unmarshal XML documents that contain simple type root elements.
