Sitemap for pages that aren't on menus

[RockitSEO]

I have a site that has pages that has a large number, about 3,000, pages that have static URLs, but no internal links and are not connected to the menu. The pages are pulled up through a user-initiated selection process that builds the URL as they make their selections, but,as I said, the pages already exist with static URLs.

The question: should the sitemap for this site include these 3,000 static URLs? There is very little opportunity to optimize the pages in any serious kind of way, if you feel that makes a difference. There is also no chance that a crawler is going to find its way to these pages through the natural flow of the site. There isn't a single link to any of these pages anywhere on the site.

Help?

These should be in a sitemap if they are unique and useful for the end-user. If not, leave them off as they may do more bad than good.
