For the Read Attribute Response frame there is really no difference. While an
array in ZCL is a ordered sequence of elements, elements in a set have no
associated order and are unique. A bag is a set without the restriction that
elements must be unique (comparable to a multi_set in STL as opposed to a set,
for example). The difference is how such attributes are managed and accesses by
commands like Write Attributes Structured etc.
I don't have capture files for theses cases because such attributes are used
sparingly, but I can certainly create some. This will take a while because I
need to establish an appropriate test setup.
