From time to time, Microsoft may publish preview or pre-release versions of Open Specifications for community review and feedback. The preview periods for each specification presented in this way are determined by the individual teams responsible for the documentation. Not every specification will be published for preview. After the preview period, the preview specifications will be published in the appropriate location in the overall Open Specifications library for further reference. To provide feedback for any preview specification, please follow the instructions for the specific document as outlined. You can always provide feedback for published Open Specifications by using the Open Specification forums at: http://social.msdn.microsoft.com/Forums/en-US/category/openspecifications. We look forward to your feedback.
