• Note that while the data type is array[string], the parameter value constructed by clients can be either:
• Multiple instances of the parameter with distinct values, e.g. foo=bar&foo=baz translates to values bar and baz for parameter foo
• One value (with no delimiter), e.g. foo=bar
• Comma-separated list of strings, e.g. foo=bar,baz translates to the values bar and baz for parameter foo
  • NOTE: character encoding of the comma (,) character (%2C) as a delimiter is not supported
  • Parameter values can contain commas, but they must be encoded, e.g. foo=bar,baz%2Czab translates to the values bar and baz,zab for parameter foo
