Currently it's rebuilt on every request. Some parts of the sitemap come
from a DB to serve the rather static pages (their content is stored in
flat files on disk and just put into a global page template when the
page is requested), other parts are added by some components of the
framework. My 'admin' module for example adds its own section to the
sitemap as the entry point for all the admin components and plugins.

If this should become a bottleneck one day, then I might implement some
kind of caching, but currently the performance is OK. The bottlenecks
are somewhere else.
