I don't see why a similar approach couldn't be taken in your container.

I will not provide the classifier container with a push_back or push_front method, instead I will use insert, I suppose it is just about the meaning of sequence, I expect a sequence to keep an order on items while container means just a collection of items in not a particular order.

The sequence is just a collection of elements which can be iterated through from begin to end. It has nothing to do with the order of elements in it or where these elements are stored. vector, set and unordered_set are all sequences, although these containers imply different element ordering strategies.
