$arParams['INPUT_NAME'] - input name for value
$arParams['INPUT_NAME_STRING'] - input name for textarea (may be useful to get original value set by user)
$arParams['INPUT_VALUE'] - starting value. can be comma-separated string of IDs or array of IDs.
$arParams['INPUT_VALUE_STRING'] - starting value as string for textarea. Tokens like "Lastname Name <Email> [id]" will be parsed automatically. Tokens may be comma-separated, semicolon-separated or newline-separated.

if both INPUT_VALUE_STRING and INPUT_VALUE are specified, INPUT_VALUE will be ignored. INPUT_VALUE_STRING may be more preferrable by the cause of interface performance.

Input has two results: list of user IDs as array (INPUT_NAME) and original text typed by user (INPUT_NAME_STRING).

$arParams['CONTROL_ID'] - ID for external events handling

$arParams['INPUT_NAME_SUSPICIOUS'] - input for some suspicious tokens such as email addresses.
