Rely on JADN

[dlemire60]

This PR updates the LS to rely more on the JADN Specification

• JADN is added as the reference for the naming conventions in 1.2.3.1
• Section 3.1 is simplified to focus on information essential to the self-contained readability of the LS
• Fix OASIS namespace form in 3.1.4 to align with OASIS and (new) TC conventions
• Appendix F has been deleted.
• Appendix G has been re-lettered to F
• The TOC has been updated.

TOC may not need to include Contents and Table 3-1.
New line 529 introduces a typo in serialization.

Approved at 13 December working meeting. No objections raised to "lazy consensus email". Merging.
