5.8.2 Encoding Rules for different kinds of DataTypes

products. Examples of Built-in DataTypes are Int32 (see 8.26 ) and Double (see 8.12 ). Simple DataTypes are subtypes of the Built-in DataTypes , which are handled on the wire like ... Simple DataType is Duration . It is handled on the wire as a Double but the Client can read the DataType Attribute and thus interpret the value as defined by Duration
