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>
