As described in the "Release Notes" of the documentation, XML archives don't work with
gcc 3.2 due to a bug in that version of gcc. I'm now working on draft # 12 and its
possible that this problem may be worked around. It doesn't appear in gcc 3.3

You assumption is correct. It is my intention that the xml archive trap at compile
time any attempt to serialize anything not wrapped as a name-value pair. I'll
look into this.

Thanks for helping with this.
