Good points Dave.

it's not really meant to be evaluated with the idea that it will be 
incorporated into Boost, since it's extremely intrusive and not really 
conducive to adding to projects. The announcement was really just a 
heads up for the list that this thing exists, and it might be useful 
for some projects where you read and write data from XML files.

I have written this as part of another project, and thought that I 
would go "free" with it straight away, because I looked around myself 
for XML persistence and couldn't really find anything of use to me 
(they all involved some type of preprocessing which I hate. at least 
this thing you can just bolt on to any class from the outside). This 
scheme also uses "pure" patterns like Visitor, Abstract factory, 
Composite to do it's stuff.

There are two small parts of this called "cppreflect" and "cpppersist" 
which would probably make nice additions to Boost, since they are very 
small, simple and general, but I'm really busy at the moment getting 
some other stuff going and don't really have time to push this.

I'd really rather get a project written using this stuff as a kind of 
"body of work" using it rather than try to push it on the group at such 
an early stage.

Thank's for looking at it though!

Paul.
