Hi Patrick,

There is no naming convention for an attribute stored in a variable,
and in netCDF-3 there is no way to store multiple strings in a single
attribute without using some sort of convention for the string
separator.  One widely used convention that is used for the global
"history" convention is to use an embedded newline in the string to
separate string values.  That won't work if your string values can
include newline characters, but otherwise would be OK.  However, the
reading program would have to know about this convention to parse the
multiple string values using the newline separators.

This is one of the benefits of the string primitive type in netCDF-4,
supporting attributes with multiple string values.
