Sitemap pagination support ?

[HarrisonQi]

Thanks for create this plugin. It's nice.

Is there any plan for sitemap pagination?

for example:

- sitemap.xml
   - sitemap-1.xml
   - sitemap-2.xml

If I have a plenty of articles, sitemap.xml will very large, and some of search engine limit the size of sitemap.

Is there any solutions for this? Thank you very much!
