/**
 * Validate the given package name for the given source and compliance levels.
 * <p>//from w  ww.j a va 2s.com
 * The syntax of a package name corresponds to PackageName as
 * defined by PackageDeclaration (JLS2 7.4). For example, <code>"java.lang"</code>.
 * <p>
 * Note that the given name must be a non-empty package name (that is, attempting to
 * validate the default package will return an error status.)
 * Also it must not contain any characters or substrings that are not valid
 * on the file system on which workspace root is located.
 *
 * @param name the name of a package
 * @param sourceLevel the source level
 * @param complianceLevel the compliance level
 * @return a status object with code <code>IStatus.OK</code> if
 *      the given name is valid as a package name, otherwise a status
 *      object indicating what is wrong with the name
 * @since 3.3
