2.2.4.2 NamedPropertyInformation Structure

The NamedPropertyInformation structure provides context to any named properties that are present in the structure it precedes. For every distinct (unique) named property used in the structure it precedes, the NamedPropertyInformation structure contains one property ID – named property pair.

The format of the NamedPropertyInformation structure is as follows. Note that if there are no named properties to be listed, the NamedPropertyInformation structure reduces to a 2-byte value of 0x0000.

NoOfNamedProps (2 bytes):  An integer that specifies the number of named property mappings that are packed in this structure. If no named properties are used in the structure that follows the NamedPropertyInformation structure, the value of this field MUST be 0x0000 and no other fields are present.

PropIds (variable):  An array of property IDs, each of which is a value of 0x8000 or greater and uniquely identifies the named property within an extended rule. There MUST be one property ID in this array for each PropertyName structure in the NamedProperties field.

NamedPropertiesSize (4 bytes):  The total size, in bytes, of the following fields. Only present if NoOfNamedProps is greater than zero.

NamedProperties (variable):  An array of PropertyName structures, each of which contains details about a named property. The format of the PropertyName structure is specified in [MS-OXCDATA] section 2.6.1. The PropertyName structures in this field MUST coincide with the property IDs in the PropIds field.
