2.2.12 Shared Feature

  • Article

A shared feature is a mechanism that enables different application features to share a common set of record types. For an enumeration of the types of shared features, see SharedFeatureType (section 2.5.237). For each type of shared feature the required records vary. All shared features use the following:

  • Common information stored in a FeatHdr (section 2.4.112) or FeatHdr11 (section 2.4.113) record. There MUST be one FeatHdr (section 2.4.112) or FeatHdr11 (section 2.4.113) record for each type of shared feature used in one of the Workbook substreams (section 2.1.7.20).

  • Instance specific feature data stored in a Feat (section 2.4.111), Feature11 (section 2.4.114), or Feature12 (section 2.4.115) record. There MUST be one or more Feat (section 2.4.111), Feature11 (section 2.4.114), or Feature12 (section 2.4.115) records for each instance of a shared feature.

Some shared features require other feature-specific records. See FEAT (section 2.1.7.20.6) and FEAT11 (section 2.1.7.20.6) records for additional records used for shared features.
