ID-CS4: Trouble observing XMLTag changes to page elements (or rather their stories)...

Question

I have created a small project that uses the same approach to monitoring stories as the one used in the GotoLastTextEdit sample project.
The GotoLastTextEdit project example does the following:
- Sets up a responder that monitor open/close signals for documents basically to ensure stories in existing documents gets observers attached.
- The responder also reacts to the NewStory/DeleteStory signals to attach observers to newly created stories.
- The observer simply listen for IID_ITEXTMODEL events on the stories.
Since I'm interrested in xml tagging related changes and not changes to the text, I've changed the IID_ITEXTMODEL to IID_IIDXMLELEMENT. I'm however still looking for events on the TextStoryBoss.
This approach seems to work. If I create a new document and add some textframes i get notifications whenever I tag/untag/change (tagging) one of them. The really weird part is that if I open a previously saved document nothing works. I get no notifications neither for existing nor for new textframes. Debugging reveals that the observer seems to be attached correctly for both existing and new stories.
If I change IID_IIDXMLELEMENT back to IID_ITEXTMODEL and listen for changes to the text everything works as expected for both new and existing documents.
So how do I get IID_IIDXMLELEMENT notifications to work for existing documents?
Any clues would be helpful...
Additional info: This was only tested on Windows, InDesign CS4.

I'm confused by your post and code.  Adobe has a function to do this.  In the Insert Toolbar under the Tab "Forms" there is an option to create a jump menu.  The only options that menu gives you is the same window or a frame on the page (a very outdated action looking at it now).  But with basic knowledge of links you insert the menu and you will get code like:
  <select name="jumpMenu" id="jumpMenu" onChange="MM_jumpMenu('parent',this,0)">
The "parent" denotes that this will open in the same window.  If you change that to "blank" then it will open in a new window.  A "Go" button is optional and also available in the DW GUI when you set up a jump menu.
