Re: [ogpx] type-system : guidance for binary serialization implementers

["Robert G. Jakabosky" <[e-mail]>]

Here is a link to the LLSD binary implementation from libopenmetaverse:
http://openmetaverse.org/viewvc/index.cgi/omf/libopenmetaverse/trunk/OpenMetaverse.StructuredData/LLSD/BinaryLLSD.cs?revision=2507&view=markup

The code is BSD licensed so I don't think there is a problem with people on 
this list reading it.

It handles missing closing tags or wrong "object counts" by throwing an 
exception, which would cause it to reject malformed LLSD messages.  I think 
this is the best way to handle any malformed LLSD message, weather it is in 
binary/JSON/XML format.

Also it doesn't check for duplicate map keys.  Only the last key/value pair 
with the same key would be kept.  We will have to decide if duplicate keys 
are allowed by the spec.
