[boost] serialization of vector<string>

I am using boost 1.32. When I serialize a string, no metadata is written, as 
implementation_level<string> is set to primitive_type in 
serialization/string.hpp. However, when I serialize a vector<string>, I end up 
with metadata, because implementation_level<vector<string> > is not set anywhere 
and therefore defaults to object_class_info.

Every other primitive type appears to be covered by 
BOOST_SERIALIZATION_COLLECTION_TRAITS and therefore 
implementation_level<vector<T> > is object_serializable for every other 
primitive type. 

I checked in 1.33 and there don't appear to be any relevant changes, but I could 
be wrong.

My question: is this an omission; that is, should 
implementation_level<vector<string> > be object_serializable? (And similarly for 
other collections of strings.)

Thanks,

Ben
