Which of the following version numbers is used by the TOGAF standard to denote a high-level outline of an architecture?

In the context of TOGAF, the designation of "Version 0.1" is correct as it signifies a high-level outline of an architecture. This version typically represents early drafts or initial conceptualizations of the framework, serving as a foundational structure that allows for further development and refinement. These initial stages are crucial as they set the groundwork for subsequent, more detailed versions, focusing on the overarching principles and guidelines that will be expanded upon in later iterations.

This version number emphasizes that while it is a preliminary outline, it is intended to guide early architectural endeavors before moving to more robust and comprehensive formats. Each increment in versioning reflects significant advancements and additions in the framework's development, but "Version 0.1" is specifically about presenting a basic outline.
