A PropCode entry in the DeviceData INF file section (see the example in Vendor-Extended Features) lists all the vendor-extended property codes, separated by commas. For each property code, an entry of the form PropCodeXXXX must be present, where XXXX is the code value in uppercase hexadecimal. 專案應該列出 WIA 屬性代碼和文字描述 （不需要當地語系化） ，以引號括住。
WIA 屬性碼應該介於 0x9802 和 0x11802之間，這是廠商定義的 WIA 裝置屬性定義的範圍。 The properties can be accessed through the IWiaPropertyStorage::GetPropertyStream and IWiaPropertyStorage::SetPropertyStream methods, which are described in the Microsoft Windows SDK documentation.
