The mechanism is propietary as storing a non XML document in a XCAP server is 
not a IETF/XCAP standard, the naming convention, the transfer mode, the icon 
image requeriments (size, formats)... all is propietary.

Replace "propietary" with "non standard" if you prefer, but the concept is the 
same: non standard features/specs on top of real standars (SIP and XCAP), so 
just the clients and servers managed by same vendor (AG) will implement them.

But as I already said, the main problem here are the IETF's XCAP specs as they 
are incomplete and don't provide needed features (as icon storage). But I 
don't agree if the proposed solution is adding these features using vendor 
propietary specs. If at least they were really well documented...
