Re: [mmox] XML serialization

Catherine... Jon...

can you create a proposal for a next generation XML serialization?

the existing serialization is in current use by SL, OpenSim and PyOGP,  
so there's probably going to be a lot of resistance to changing  
something that currently works and is deployed.

keep in mind, however, that OGP does not use XML to represent it's  
PDUs, it uses LLSD. XML is one of three defined serializations of  
LLSD. it's a subtle difference, but important.

for instance... is there a benefit to explicitly adding support for  
namespaces to the XML serialization? there was a bit of discussion  
about this amongst some AWG members, and the consensus was... "why  
bother? the XML (presentation layer) is not the place where you want  
to extend the PDU... you want to extend it in the LLSD / LLIDL  
definition of the interaction."

but, i still think it's an interesting idea as it might allow systems  
that use XML serialization exclusively to extend display and  
distribution options of various PDUs.
