/**
 * This class is for Jakarta XML Binding permissions. A {@code JAXBPermission}
 * contains a name (also referred to as a "target name") but
 * no actions list; you either have the named permission
 * or you don't.
 *
 * <P>
 * The target name is the name of the Jakarta XML Binding permission (see below).
 *
 * <P>
 * The following table lists all the possible {@code JAXBPermission} target names,
 * and for each provides a description of what the permission allows
 * and a discussion of the risks of granting code the permission.
 *
 * <table class="striped">
 * <caption style="display:none">Permission target name, what the permission allows, and associated risks"</caption>
 * <thead>
 * <tr>
 * <th scope="col">Permission Target Name</th>
 * <th scope="col">What the Permission Allows</th>
 * <th scope="col">Risks of Allowing this Permission</th>
 * </tr>
 * </thead>
 *
 * <tbody style="text-align:left">
 * <tr>
 *   <th scope="row">setDatatypeConverter</th>
 *   <td>
 *     Allows the code to set VM-wide {@link DatatypeConverterInterface}
 *     via {@link DatatypeConverter#setDatatypeConverter(DatatypeConverterInterface) the setDatatypeConverter method}
 *     that all the methods on {@link DatatypeConverter} uses.
 *   </td>
 *   <td>
 *     Malicious code can set {@link DatatypeConverterInterface}, which has
 *     VM-wide singleton semantics,  before a genuine Jakarta XML Binding implementation sets one.
 *     This allows malicious code to gain access to objects that it may otherwise
 *     not have access to, such as {@code java.awt.Frame#getFrames()} that belongs to
 *     another application running in the same JVM.
