How in SetPropertyValuesEx to access not the value id for a property of the List type, but XML_ID?
For example
$ELEMENT_ID = 33; // element code
$PROPERTY_CODE = "Seasons"; // property code
$PROPERTY_VALUE = "184"; // property value
184 it is not static but periodically interposed. Therefore, you need to refer to xml_id. But in SetPropertyValuesEx, I did not find an example of how this can be done.

Because there is no such possibility, the documentation says about it.
To do this, you get all the values ​​​​of the list separately, look for your xml_id there, find out its id and substitute it,
i.e.

$db_enum_list = CIBlockProperty::GetPropertyEnum("BREND", Array('sort' => 'asc'), Array("IBLOCK_ID"=>$arParams["IBLOCK_ID"]));
while($ar_enum_list = $db_enum_list->GetNext())
{$arrProp[]=$ar_enum_list;}//получили значения списка, если требуется именно по xml_id, то сразу формируйте с ключами нужными
//$arrProp[$ar_enum_list['XML_ID']]=$ar_enum_list; - лень принтовать проверьте у себя сами правильность написания
//ну а далее 
// пусть будет id = 184, xml_id=leto, value=лето
$PROPERTY_VALUE = $arrProp['leto']['id'];

more or less like this
