This document describes the schema for the chainer package XML. This XML is generated at build time and added to a package containing an installer. There are several types of installers (RTM, Service Pack, QFE) that all use this XML. ISSUES LIST: * Currently the MSI, Configuration, and Upgrade extension data is at the root package level. In order to generalize the package XML they should probably be moved to an extension subnode. @Owner: scottkon
