Detailed Description

Tree node for sharing serialized tags.

See PacketTagList for a discussion of the data structure.

Internal:: Unfortunately this has to be public, because PacketTagIterator::Item::GetTag() needs the data and size values. The Item nested class can't be forward declared, so friending isn't possible.

We use placement new so we can allocate enough room for the Tag type which will be serialized into data. See Object::Aggregates for a similar construction.
