Great.  Looking good.

I have added an openDeclaration function which takes a qualified identifier 
and a SimpleRange instead of nodes, try them.

BTW, if you have multiple identifier ast node types, you can pass the base ast 
node class to the template as the NameT type, then you can support them 
inside your context builder.  This does lose some type safety, but you can't 
help that if you have more than one type of identifier node in your ast.
