Indeed however there are ways of persisting a model & they require at 
the end of the day a recognizable document design/format.

I have already noted how using text children of an element to use a 
value vs a std "value" attribute in the archetype xml  inflates the file 
sizes.

<A>
Some value
</A>

&
<A value=""Some value"/>

Are both persisting/serializing the same data.
