Delimiter of elements, where each element is a key/value pair, and
between key and value of an element.
Treatment of special cases:
- If an element does not contain a keyval_delim character, it is treated
as a key without a value; a null value is then reported.
- If an element contains more than one keyval_delim character, the first
occurrence is used as delimiter so that the value contains
keyval_delim characters but not the key.
- If the last character of an element is a keyval_delim character and
this is the only occurrence, the value is a non-null empty string.
Must be specified in the constructor but may be modified at any time.
