RE: Questions on modified Extended Attribute format?
You are correct. In RADIUS definitions we define attributes by specifying the format and meaning.
When we define the meaning typically we say when this attribute "when included in an access accept message it means ...." and "when included in an access request it means ...."
Now if we want to reuse the attribute (because we love the format) in a new container. We would just have to modify the meaning part of the definition by adding "when the attribute appears as part of this grouping it means ..."
Going forward if you really want to promote reuse when it is possible you would just define the syntax of the attribute and then when you define the container (grouping) which includes that attribute you would define what it means when this attribute is in a particular container/grouping.
