The Application Group Extension to the X protocol is intended to provide a framework to allow more than one program to manage X applications on the desktop. The initial use of this extension will be to insert or embed the windows of X programs into the windows of another program, such as a web browser. This extension is not intended to address larger embedding issues that, for example, OpenDoc does, such as shared menu bars, etc. Using X programs on the World Wide Web allows for greater control of the presentation and takes advantage of the existing body of X programs rather than re-implement them in another language. In addition it allows the embedding of non-X programs into web browsers by using third party products like Wabi, MAE, and WinCenter.^[1]
