Can the googlesitemap placeholders be changed via call parameters like this?
[[!GoogleSiteMap &itemTpl=`sitemapTpl` &changefreq=`[[*frequencyChange]]`]]
or do they have to be accessed via the API and setPlaceholder?
&containterTpl:
1. <urlset xmlns="[[+schema]]">
2. [[+items]]
3. </urlset>
&itemTPl:
1. <url>
2. <loc>[[+url]]</loc>
3. <lastmod>[[+date]]</lastmod>
4. <changefreq>[[+update]]</changefreq>
5. <priority>[[+priority]]</priority>
6. </url>
