UAF13 — UAF Grid and text refers to 'Architecture Extensions' View Specification - View Specification Doesn't Exist

Section 7 UAF Grid. Fig 7-1 and note e) refer to a 'Architecture Extensions' view specification:
'The Architecture Extensions view specification provides a means to extend the framework to other domains'

1) There is no 'Architecture Extensions' view specification in 8.1 View Specifications
2) The name 'Architecture Extensions' is incorrect - the subject is not the architecture but the architecture description (it describes means to extend the architecture framework not the architecture'. The name should more accurately be 'Architecture Description Extensions' or 'Architecture Framework Extensions'.
