2.1.4 Parts

A package is composed of multiple parts as specified in [ISO/IEC29500-2:2011] Section 9.1. Each part has an associated content type that specifies the format it is persisted in. Each part can also be the target or the source of a connection between two parts called a relationship, as specified in [ISO/IEC29500-2:2011] Section 9.3.

The valid parts, content types, and required and optional relationships between all parts in this package are specified in Part Enumeration.
