bottom layer:
class RawTrie<key_t, value_t>;
provide some interfaces to manipulate sub-tree, and could

second layer:
A specific RawTrie.
typedef StringTrie<value_t> RawTrie<string, value_t>;
also provide some interfaces to manipulate sub-tree

third layer:
TrieMap<value_t> - build upon the StringTrie, but can not manipulate the 
sub-tree, just provide the interfaces as stl:map and the interfaces I 
list above.

Ok, you mean that I should add this link of our discussion to the 
'additional info' of my proposal in GSoC page?
