SitemapPostRendererResource
A PostRendererResource that generates a sitemap.xml listing the root document and every subdocument as a <url><loc> entry with absolute URLs.
Requires com.quarkdown.core.context.options.HtmlOptions.baseUrl to be set via .htmloptions; if absent, no sitemap is emitted. The sitemap is also skipped when the document has no subdocuments.
Parameters
