	Nah, it's morning.. Coffee..  ;-P

	The above already exists as the xpt struct in the common libs, as shown
below:

typedef struct xpt_struct
{
	int type;
	int status;
	char *name;
	char *value;
	jpair *attributes;
	struct xpt_struct *children;
	struct xpt_struct *next;
	struct xpt_struct *parent;
} xpt;

	All your above really does is objectasize (IS that a word?) this type of
thing.

	See above, only thecommon lib current has functions in xpt.c that do what
your talking about.  Here's an idea.  We could do exactly what your talking
about, but write some C++ wrappers around the current code, hence, we have
both a C and C++ way of doing things..

	I am doing this current in the Windows client, using Visual C++.  My
original idea was exactly what your talking about, making a generic C++
class, in my case, stored in a DLL that could be used by any program to
'Jabberify' it easily.

	I like where your going, but I think we can use our current code base to do
this fairly easily..
