An identifier part character is any character for which the +// method Character.isJavaIdentifierPart returns true. +// - Identifiers cannot be the names NULL, TRUE, or FALSE. +// – Identifiers cannot be NOT, AND, OR, BETWEEN, LIKE, IN, IS, or +// ESCAPE. +// – Identifiers are either header field references or property references. The +// type of a property value in a message selector corresponds to the type +// used to set the property. If a property that does not exist in a message is +// referenced, its value is NULL. The semantics of evaluating NULL values +// in a selector are described in Section 3.8.1.2, “Null Values.” +// – The conversions that apply to the get methods for properties do not +// apply when a property is used in a message selector expression.
