In the latest version of DW, subscribens was added to allow subscription to a namespace. When printing buttons in a template using tpl_button, subscribe to page changes and namespace changes are bundled together. However, if you use tpl_actionlink, you can refer to one or the other. In my case, I want to use tpl_button, but want the subscribe to page changes to appear in a different place than subscribe to namespace changes. Both tpl_button and tpl_actionlink should have the same behaviour.
