Introduction

All references to 'MEF Forum' or 'MEF' in the release documentation, links, and
YAML files should be interpreted as references to 'Mplify Alliance' and
'Mplify' respectively. Since this release coincides with the transition of the
name of MEF Forum to Mplify Alliance, changes were not made to all the files in
this release. Standards that were already published will retain the "MEF" name.

Management functions of the Service Orchestration Functionality (SOF) at the
