The following table contains the beginning of a User Defined property set (section 2.3.3.2.3). In this table, there is an array, rgUserProps. Each element in rgUserProps is a PropertyIdentifierAndOffset structure ([MS-OLEPS] section 2.19). The structure of this section of the User Defined property set (section 2.3.3.2.3) is similar to that described in Document Summary Information Property Set Overview (section 3.2.2). The major difference is that in the User Defined property set (section 2.3.3.2.3) most propId values do not have a meaning defined by this specification, but instead have a meaning defined by their names as found in the Dictionary property (section 3.2.3.1).

Figure 24: Overview of a User Defined property set
UserDefinedProperties: UserDefinedProperties is a PropertySet as detailed in [MS-OLEPS] section 2.20.
cbSection: 0x00000420 indicates the count of bytes from the beginning of the UserDefinedProperties property set (0x00000298) to the end of the last property in the property set, the CriticalSection_Link property (section 3.2.3.4). If the size is calculated as 0x0000069A + 0x001C - 0x00000298, it actually results in a size of 0x0000041E instead of 0x00000420. This is because the property set is padded to a multiple of 4 bytes. After the end of the CriticalSection_Link property (section 3.2.3.4) property, there are 2 bytes of padding to make the count of bytes of the property set a multiple of 4 bytes, resulting in a length of 0x00000420.
cProps: 0x00000009 indicates that this User Defined property set (section 2.3.3.2.3) contains nine properties.
rgUserProps: This is the container of an array of PropertyIdentifierAndOffset structures. In this example, there are nine elements, one for each property.
rgUserProps.PidOffsetElement-1: Dictionary (Dictionary property).
rgUserProps.PidOffsetElement-1.propId: 0x00000000 indicates that there is a Dictionary property value at the stream offset indicated by the dictionaryOffset value.
rgUserProps.PidOffsetElement-1.dictionaryOffset: 0x00000050 indicates that the beginning of the Dictionary property data is 0x00000050 bytes after the beginning of the UserDefinedProperties property set (0x00000298). In this example, the Dictionary property begins at offset 0x000002E8. See the Dictionary property example (section 3.2.3.1).
rgUserProps.PidOffsetElement-2: CodePage (VT_I2 TypedPropertyValue property).
rgUserProps.PidOffsetElement-2.propId: 0x00000001 indicates that there is a CodePage property value at the stream offset indicated by the codepageOffset value.
rgUserProps.PidOffsetElement-2.codepageOffset: 0x000000D2 indicates that the beginning of the CodePage property data is 0x000000D2 bytes after the beginning of the UserDefinedProperties property set.

rgUserProps.PidOffsetElement-4.hyperlinksOffset: 0x000000E6 indicates the user-defined property with propId 0x00000003 begins 0x000000E6 bytes after the beginning of the UserDefinedProperties property set. In this example, this property begins at offset 0x0000037E. See the Hyperlinks Property Example (section 3.2.3.3).
rgUserProps.PidOffsetElement-5: User-defined property.
rgUserProps.PidOffsetElement-5.propId: 0x00000004 indicates there is a user-defined property value at the stream offset indicated by the propOffset value.
