I think that the most useful breadcrumbs are usually found in very deep sites so that you don't lose your place, and often come "generated" by some sort of backend system.

However, you can do the breadcrumb trails manually in Xara in the same way as you might do the "you are on this page" graphic that usually shows up in a navigation bar. If you are on the "Services...web design" page of the site, then you would put the links up top to the main services page and display the current page. This really would only be an illusion to the website viewer that the site "knew" where they were, but really, they would be static links on the page in this case, just like any other links you might put there.

Make sense?

Does that help at all?
