        'urls'=> [
            // your additional urls
            [
                'loc' => '/news/index',

Add behavior in the AR models, for example:

use katech91\sitemap\behaviors\SitemapBehavior;

public function behaviors()
{
    return [
        'sitemap' => [
            'class' => SitemapBehavior::className(),
            'scope' => function ($model) {
                /** @var \yii\db\ActiveQuery $model */
                $model->select(['url', 'lastmod']);
                $model->andWhere(['is_deleted' => 0]);
            },
            'dataClosure' => function ($model) {
                /** @var self $model */
                return [
                    'loc' => Url::to($model->url, true),
                    'lastmod' => strtotime($model->lastmod),
                    'changefreq' => SitemapBehavior::CHANGEFREQ_DAILY,
                    'priority' => 0.8
                ];
            }
        ],
    ];
}

Add a new rules for urlManager of your application's configuration file, for example:

'urlManager' => [
    'rules' => [
        ['pattern' => 'sitemap', 'route' => 'sitemap/default/sitemap-index', 'suffix' => '.xml'],
        [
            'pattern' => 'sitemap_<name:.+?><delimetr:_+><page:(\d+)>',
            'route' => 'sitemap/default/sitemap',
            'defaults' => [
                'delimetr' => null,
                'page' => null
            ],
            'suffix' => '.xml',
        ]
    ],
],

Sitemap creates by following scheme: sitemap.xml containes SitemapIndex with list of local sitemaps and url's sitemap:

<?xml version="1.0" encoding="UTF-8"?>
<sitemapindex xmlns="http://www.sitemaps.org/schemas/sitemap/0.9"
               xmlns:image="http://www.google.com/schemas/sitemap-image/1.1"
               xmlns:news="http://www.google.com/schemas/sitemap-news/0.9">
    <sitemap>
        <loc>http://localhost/sitemap_urls.xml</loc>
    </sitemap>
    <sitemap>
        <loc>http://localhost/sitemap_news.xml</loc>
    </sitemap>
</sitemapindex>

local sitemaps (for example sitemap_news.xml) contains addresses of news if number of articles is less than 1 000:, _(*5)

<?xml version="1.0" encoding="UTF-8"?>
<urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9"
        xmlns:image="http://www.google.com/schemas/sitemap-image/1.1"
        xmlns:news="http://www.google.com/schemas/sitemap-news/0.9">
    <url>
        <loc>http://localhost/news/first</loc>
        <lastmod>2016-01-01T00:00:00+00:00</lastmod>
        <changefreq>daily</changefreq>
        <priority>0.8</priority>                
    </url>
    <url>
        <loc>http://localhost/news/second</loc>
        <lastmod>2016-01-11T00:00:00+00:00</lastmod>
        <changefreq>daily</changefreq>
        <priority>0.8</priority>
        <news:news>
    </url>
    </urlset>

If number of articles bigger local sitemap contains addresses of subsitemaps: html <?xml version="1.0" encoding="UTF-8"?> <sitemapindex xmlns="http://www.sitemaps.org/schemas/sitemap/0.9" xmlns:image="http://www.google.com/schemas/sitemap-image/1.1" xmlns:news="http://www.google.com/schemas/sitemap-news/0.9"> <sitemap> <loc>http://localhost/sitemap_news_0.xml</loc> </sitemap> <sitemap> <loc>http://localhost/sitemap_news_1.xml</loc> </sitemap> <sitemap> <loc>http://localhost/sitemap_news_2.xml</loc> </sitemap> </sitemapindex>, _(*6)
