This part of ISO/IEC 23001 provides a standardized set of technologies for encoding XML documents. It addresses a broad spectrum of applications and requirements by providing a generic method for transmitting and compressing XML documents.

This part of ISO/IEC 23001 specifies system level functionalities for the communication of XML documents. It provides a specification which will:

• enable the development of ISO/IEC 23001-1 receiving sub-systems, called ISO/IEC 23001-1 Terminal, or Terminal in short, to receive and assemble possibly partitioned and compressed XML documents
• provide rules for the preparation of XML documents for efficient transport and storage.

The decoding process within the ISO/IEC 23001-1 Terminal is normative. The rules mentioned provide guidance for the preparation and encoding of XML documents without leading to a unique encoded representation of such documents.
