In the next version
For those of us with large sitemaps, would it be possible for the unlimited generator to automatically impose Google limitations? For example, if a sitemap (after decompression) exceeds 10 MB AND/OR has 50,000 Urls or more, then another filename is started.
Sitemap.xml (or Sitemap.xml.gz) = 1 - 50,000 URLS @ 10 MB.
Sitemap-2.xml (or Sitemap-2.xml.gz) = 50,001 - 100,000 URLS @ 10 MB.
But perhaps it will look something like this
Sitemap.xml (or Sitemap.xml.gz) = 1 - 38,000 URLS @ 10 MB.
Etc., Etc., Etc.
