How to implement code completion for annotation's array parameter?

I have implemented code completion for annotation's string parameter with following code:


public void registerReferenceProviders(PsiReferenceRegistrar registrar) {
        registrar.registerReferenceProvider(
              registrar.registerReferenceProvider(
                PsiJavaPatterns.literalExpression().annotationParam("org.unitils.dbunit.annotation.DataSet", "value"), new URIReferenceProvider(), PsiReferenceRegistrar.HIGHER_PRIORITY);
    }

The above code code can work for @DataSet("xxx.xml"), but I can not work for array type. No completion for  @ DataSet({"xxx.xml"}),  Any idea?

code for @DataSet


@Target({TYPE, METHOD})
@Retention(RUNTIME)
@Inherited
public @interface DataSet {


    /**
     * The file name of the data set. If left empty, the default filename will
     * be used: first 'classname'.'testMethodname'.xml will be tried, if that file does not exist,
     * 'classname'.xml is tried. If that file also does not exist, an exception is thrown.
     *
     * @return the fileName, empty for default
     */
    String[] value() default {};
}
