What does the term 'substance' refer to regarding communication records?

The term 'substance' in the context of communication records refers to key information about the content and context of the communication itself. This includes the main topics discussed, the intention or purpose behind the communication, and any substantive information being conveyed. Understanding the substance is essential for analyzing the effectiveness and relevance of the communication, especially in legal and regulatory interpretations.

In contrast, the method of transmission pertains to how the communication was delivered (e.g., email, phone call), while the emotional tone relates to the feelings expressed in the communication, but does not capture the detailed content itself. Details about the communication's delivery might involve logistical aspects such as timing and method but do not reflect the core information exchanged. Thus, 'substance' specifically addresses the heart of the communication, making it critical for documentation and analytical purposes in many contexts.
