Subject RE: C++ To Do List

Xerces-C is what I am using for the SOAPEnvelope classes.  OpenSLL is fine
as long as it has ports for all of the major OS's (I'm not too familiar with
the product).

I can take #2 if you're ok with using OpenSLL for SSL support ?

Which parser are we using ?, Xerces-C has some multi platform network
support we should be able to re-use.
