Status
Scope
The IPC-2571 document provides introductory and explanatory information about this standard and
includes other elements that are also required or used. The IPC-2571 dictates the required package
structure and XML format for information exchange using any of the subsequent IPC-257x standards
such as this one. In any such exchange, a Product Data eXchange package must be defined which
contains at a minimum a single pdx.xml file. This file in turn is required to contain a single
ProductDataeXchangePackage element, and may contain any number of other elements from this
specification. The Product Data eXchange package may optionally contain or refer to related external
files.
