Yeah. The clearest thing in the RFC is the ABNF grammar. However, even that leaves out common cases like white space outside of quoted fields, which most people would expect to be trimmed. Also, I think most people would expect leading/trailing white space to be trimmed, even in unquoted fields. I think I'll break out my flex/lemon tools tonight and make a CSV parser.
