This sort of material would belong under a category best described
as "Adjunctive comments" or, more simply, "discussion".

Under the dictum that, in well-formed english, each paragraph contains
one main idea, the unit of labeling would the paragraph. Every paragraph
in a document would therefore need a label, but providing them need not
be onerous. The reason? Because in a "well-formed" hierarchy, it should
be possible to default the node type.

When you click the "reply" button in your browser/editor/email system,
the node that is created might automatically get the "discussion" type,
for example. In an IBIS conversation, a new entry at the top most level
would automatically be a question. A child node created under a question
would automatically be an alternative. Under that would be arguments
