SACM — ARM: Page 16, section 8.2.9

“A Claim that is intentionally declared without any supporting evidence or reasoning (in the recorded Argument) ...”: It is clear how evidence supports a claim (through the AssertedEvidence link). It is less clear how reasoning supports a Claim; the reasoning itself is represented in the “content” attribute of an ArgumentReasoning element, which can be associated with an AssertedInference, which in turn may have the Claim as its target; but this an indirect association.

In section 9.2.9 (Claim Class)
a) delete first sentence, and replace by "Claims are used to record
the propositions of any structured Argumentation"
b) delete the content under the Semantics Sub heading, and replace
with:
"
The core of any argument is a series of claims (premises) that are
asserted to provide sufficient reasoning to support a (higher-level)
claim (a conclusion).
A Claim that is intentionally declared without any supporting
evidence or argumentation can be declared as being assumed to be
true. It is an assumption. However, it should be noted that a
Claim that is not 'assumed' (i.e. assumed = false) is not being
declared as false.
A Claim that is intentionally declared as requiring further evidence
or argumentation can be denoted by setting toBeSupported to be true.
