"Notice: In the frontend the setting of default constants will only
apply to a branch of the tree if a template record is found on that
page (or if a template record is set for "next level"). In other
words: If you want the Page TSconfig constant defaults to affect only
a certain branch of the page tree, make sure to create a template
record (a blank one will do) on the page that carries the Page
TSconfig information."
