Description

I ran the NSL-KDD data set (http://nsl.cs.unb.ca/NSL-KDD/) through the ARFF integration. The process failed to parse the arff formatted file. The file has quoted identifiers:

@relation 'KDDTrain-20Percent'
@attribute 'duration' real
@attribute 'protocol_type'

{'tcp','udp', 'icmp'}

The quotes caused the problem. The "official" arff BNF shows that quotes should be supported:
