Mixing dynamic and fixed items in Silverlight TreeView

I'm attempting to create a TreeView in Silverlight that contains both fixed elements and databound ones. I am able to produce one that creates the desired effect, but it's not perfect - it highlights parent+child nodes as a single TreeViewItem.

The effect I am trying to achieve is:

PersonName

|-Age:

|-Hair Colour:

|-Pets

| |-PetName

| | |-Species:

| | |-Size:

| |-PetName

| . |-Species:

| . |-Size:

|-Friends

. |-Name:

. |-Favourite Comic: So elements like 'Pets' and 'Friends' should always appear for a person, with their items beneath them. How can these be templated?

I've looked at the example here but it only has static elements above the databound ones. If the structure was DataboundConference-->Teams-->TeamName,TeamName,TeamName instead of DataboundConfere开发者_StackOverflow中文版nce-->TeamName,TeamName,TeamName, it'd be exactly what I wanted.

I hope I've explained this correctly...
