/**
* <p>Specification for how to convert/render JavaDocData into an XML annotation. As an example, let us
* assume that a class contains the following field and JavaDoc:</p>
* <pre>
* <code>
* {@literal /}**
* The last name of the SomewhatNamedPerson.
* *{@literal /}
* {@literal @}XmlElement(nillable = false, required = true)
* private String lastName;
* </code>
* </pre>
* <p>The standard SchemaGen generation creates a complex type with the following element declaration:</p>
* <pre>
* <code>
* <xs:element name="lastName" type="xs:string" />
* </code>
* </pre>
* <p>However, if we use the jaxb2-maven-plugin for post-processing, we can inject the javadoc as an XSD
* annotation into the resulting schema, yielding the following result:</p>
* <pre>
* <code>
* <xs:element name="lastName" type="xs:string">
* <xs:annotation>
* <xs:documentation><![CDATA[The last name of the SomewhatNamedPerson.]]></xs:documentation>
* </xs:annotation>
* </xs:element>
* </code>
* </pre>
* <p>The JavaDocRenderer will create the content of the CDATA element within the XSD documentation annotation,
* given the JavaDocData for each field, such as the <em>lastName</em> in our example.</p>
