XMLSitemap- Is it OK to add nodes both by content type and menu? I'm making a sitemap using the XML Sitemap module.  The module and its submodules allow nodes to be added to the sitemap from the content type configuration screen as well as the menu configuration screen.

So, for example, I can add all nodes of type Basic page to the sitemap, and then I can add all links in the Primary links menu (many of which are nodes of type Basic page) to the sitemap as well.

My question: Is doing this OK?  Should I be worried about having duplication between adding the content types and adding the menus?  Or is this nothing to worry about?
There is no harm in adding both by menu and by content type (I have tested this before).  In my experience, paths will not be duplicated.

If you also add by content type, then that priority will be used, even if it is lower than the one you have set for the menu.  Also, the last modification date will be used; it doesn't get used when you add by menu.  The XML Sitemap module also checks node access rights, so only ones visible by anonymous will end up in the sitemap.

If you add by menu, the module will not output links that the anonymous user doesn't have access to.

I don't recall explicitly testing paths that exist in multiple menus, though.
