In testing the interface, it made sense to be able to 1 value/file is actually slightly more complex rule: Attributes should be ASCII text files, preferably with only one value per file. It is noted that it may not be efficient to contain only one value per file, so it is socially acceptable to express an array of values of the same type. See sysfs.txt. Proposed "sync_enable" is ugly enough, and the values really are array of values of same type, so we should be ok with nicer interface.
