Deprecated
This page aims to cover information that has been removed from various documents but which may still be relevant for the purpose of backwards compatibility. It does not explain which technologies deprecate which, only variations between versions of a particular technology.
This page aims to cover bits of specifications that have been deprecated in newer versions but which might still be relevant for one reason or another; however, it does not cover technologies that have been deprecated in favour of others. Care was taken to ensure that the "old" information is in its latest form in all the documents referenced.
