== Parameters


|===
| Name | Description

| *pos*
| An iterator to the element.


| *value*
| The value to assign. The        empty string still counts as a value.        That is, `has_value` for the element        is true.


| *key*
| The key to match.        By default, a case‐sensitive        comparison is used.


| *ic*
| An optional parameter. If        the value xref:boost/urls/ignore_case.adoc[ignore_case] is passed        here, the comparison is        case‐insensitive.
