// 4.1.3.1.  Serializing a Bare Item
//
// Given an Item as input_item, return an ASCII string suitable for use
// in a HTTP field value.
//
// 1.  If input_item is an Integer, return the result of running
//     Serializing an Integer (Section 4.1.4) with input_item.
//
// 2.  If input_item is a Decimal, return the result of running
//     Serializing a Decimal (Section 4.1.5) with input_item.
//
// 3.  If input_item is a String, return the result of running
//     Serializing a String (Section 4.1.6) with input_item.
//
// 4.  If input_item is a Token, return the result of running
//     Serializing a Token (Section 4.1.7) with input_item.
//
// 5.  If input_item is a Boolean, return the result of running
//     Serializing a Boolean (Section 4.1.9) with input_item.
//
// 6.  If input_item is a Byte Sequence, return the result of running
//     Serializing a Byte Sequence (Section 4.1.8) with input_item.
//
// 7.  If input_item is a Date, return the result of running Serializing
//     a Date (Section 4.1.10) with input_item.
//
// 8.  Otherwise, fail serialization.
