Hi
thanks for the fast reply
If you want to be sure to keep a content and a stylesheet you can set the
function isRemoveable of the templates to false (like for the template) and
change the TemplateEdit Action to allow the remove of them if there is
another Template for stylesheet or the contents. You only need a message
which say the type of the template and if there is 2 of the same type, you
can remove one of them.
