 8- **Status:** Accepted

10## Context
11
12Our documentation occasionally refers to layers 1, 2, and 3 as "lower layers" with layers 5, 6, and 7 as "upper layers." This has not proven to be universally understood, and when images provide a cascading view (with 1 at the top) the terminology becomes actively unhelpful.
13
14## Decision
15
16We will describe layers 1-3 as "Definition" and layers 5-7 as "Measurement"
17
18## Consequences
19
20- All documentation and web content must be updated

22## Alternatives Considered
23
24Several alternative terms were debated on a live working session and quickly disregarded.
