I am trying to display an item with a particular known name in a sequence. I don't know the
sequence name, but can probably determine that through the DOM API or other means.

Right. The name does varies. I hardcoded "rdf:#$imX6r" just to see how the tree would look. In
reality, I'll be using the DOM to set that attribute at runtime (or use a more advanced template
as Phil and Nickolay suggested).
The algorithm I use to determine which resource name to use is probably not relevant, but if you
care: all the resource names are cached in an associative array at startup. One of the array
properties is a URL (which is also specified in the RDF). When a user navigates to a URL which
matches one in the associative array, I want to display the <tree/> xul showing him the match and
all its properties.
