2.1.2 Part

A part is a stream of bytes as specified in [ISO/IEC-29500-2] section 9.1. Each part has an associated content type that specifies the nature and type of content stored in the part. Parts store information in binary, XML, and text formats. The valid parts, valid content types, and required relationships (section 2.1.3) between all parts in a package (section 2.1.1) are specified in Part Enumeration (section 2.1.4).

This document uses Augmented Backus-Naur Form (ABNF) as specified in [RFC5234] to specify the content of the List Definition (section 2.1.4.11) and Table Data (section 2.1.4.22) parts.
