SYSML21 — Lack of documentation of purpose and semantics of single-line and multiline notes, which can lead to data loss

The textual notation of single-line (//) and multiline (/** */) notes does not appear to be documented in either the SysML v2 or KerML specifications. These are described in the Intro to the SysML v2 Language - Textual Notation slide deck, are used extensively in example models throughout both specs, and appear in the BNF in 8.2.2.2 of the KerML Spec Beta 2.4. However, their intended use and semantics are not described anywhere in either spec. It should be important to state in the spec(s) that these notes are intended to not be part of the model, if this is still true.
