The <javadoc> declaration lets you add custom Javadoc tool annotations to schema-derived JAXB packages, classes, interfaces, methods, and fields. Note that <javadoc> declarations cannot be applied globally; they are only valid as sub-elements of other binding customizations.
The syntax for the <javadoc> customization is:
<javadoc> Contents in <b>Javadoc<\b> format. </javadoc>
or
<javadoc> <<![CDATA[ Contents in <b>Javadoc<\b> format ]]> </javadoc>
Note that documentation strings in <javadoc> declarations applied at the package level must contain <body> open and close tags; for example:
<jxb:package name="primer.myPo"> <jxb:javadoc> <![CDATA[<body>Package level documentation for generated package primer.myPo.</body>]]> </jxb:javadoc> </jxb:package>
