Thank you for the fast reply, Robert.

I'm not certain I quite understand this.  Perhaps I didn't get my 
thoughts down coherently.  I'm seeking to write my serialization like 
this (sorry I forgot to include this in my initial msg):

char some_array[5] = "test";
....
ar & make_nvp("some_array", make_char_array(some_array, 5));

And obtain the following output:

output.xml:
...
<some_array>test</some_array>

output.txt:
.... 4 test ....
---------------------------

My aforementioned make_char_array() works fine for text archives--just 
not when the result is composed with make_nvp().

Which is pretty much what my serialization wrapper is doing (this is in 
fact, what I wrote initially, before trying to make it a serialization 
wrapper).  While I can certainly do the blunt approach, it will require 
me to split my serialization function :(
