Could you please clarify what you mean by that? Do you mean the first and last tags of the archive are checked? I can't reproduce that behaviour either.
int foo = 1;
unsigned int bar =1;
// create stream & output xml archive
oarchive << BOOST_SERIALIZATION_NVP(foo);
// create input xml archive from stream
iarchive >> BOOST_SERIALIZATION_NVP(bar);
This deserializes happily.

Subject: [Serialization] Guard against attempting to deserialize the wrong type
I'm just wondering if NVP/XML archives check the name during deserialization?
I just had a problem whereby I tried deserializing an object to one type, but the archive actually contained a different (larger ) object type. The first serialized element of the object just so happened to be an unsigned int, and I was trying to deserialize an enum, so the output actually seemed sensible, and didn't cause any problems until I later deserialized the full object from the same archive, which caused a segmentation fault in the boost::serialize source (trying to get ETI from a null pointer).
I was using a polymorphic text archive, and as I mentioned above, am wondering if I switched to an XML archive if this sort of user-error would be detected.
