[Opensim-dev] Serializing parcel data in OARS (was Re: [Opensim-commits] [OpenSim Git Master Repository] master branch updated. r/10596)

[Justin Clark-Casey]

dr scofield, could we serialize/deserialize this manually, as done in 
OpenSim.Framework.Serialization.External.RegionSettingsSerializer.cs?

Otherwise I fear that there will be a lot of awkardness if the external format 
changes in certain ways (e.g. renaming of xml attributes).
