[Trinidad] tr:navigationPane - adding a tab close widget

[Renzo Tomaselli <re...@tecnotp.it>]

Hi all, I use tr:navigationPane to assembly a tabber (hint="tabs"). It 
works fine.
Now I noticed that it's fairly common for today's tabs (see Firefox, 
Eclipse, etc.) to hold a small closing icon for the purpose of removing 
that tab altogether.
This occurring besides the original behavior of the tab, handled as a 
command for selection purposes within a nodeStamp facet.
I tried to insert two tr:commandNavigationItem in the facet, but 
Trinidad complains about this, not being the expected single command.
Is there any other trick to achieve this behavior - besides cloning 
tr:navigationPane to accept a further command (either through more 
attributes or by accepting a more complex facet) ?
Comments are welcome.
