+/**
+ * Conceptually, there are three types of structured field (header) values:
+ *
+ * Item - can be an Integer, Decimal, String, Token, Byte Sequence, or Boolean.
+ * It can have associated Parameters.
+ * List - array of zero or more members, each of which can be an Item or an InnerList,
+ * both of which can be Parameterized.
+ * Dictionary - ordered map of name-value pairs, where the names are short textual strings
+ * and the values are Items or arrays of Items (represented with InnerList),
+ * both of which can be Parameterized. There can be zero or more members,
+ * and their names are unique in the scope of the Dictionary they occur within.
+ *
+ *
+ * There's also a few primitive types used to construct structured field values:
+ * - BareItem used as Item's value or as a parameter value in Parameters.
+ * - Parameters are an ordered map of key-value pairs that are associated with an Item or InnerList.
+ * The keys are unique within the scope the Parameters they occur within, and the values are BareItem.
+ * - InnerList is an array of zero or more Items. Can have Parameters.
+ * - ListEntry represents either Item or InnerList as a member of List or as member-value in Dictionary.
