Andy,

I know that the XSmiles browser has a tree control in its XForms  
implementation (http://www.x-smiles.org/) because I have used it for  
just the purpose you have in mind. It might be worth just having a  
look just to get some ideas from. I had thought that one or two other  
XForms implementations have implemented the same extension, but maybe  
not.

All the best

Mark
