[General Principles and Design]

Under the General Principles and Design section, consider adding a "Known Issues and Future Development" page or section. This section would provide implementers some visibility to known problems with the current implementation guide, as well as potential changes in a future release.

Planned future goals such as distinguishing the Emergency document use case vs minimal data set for jurisdictional adoption would be something that could be documented in this section.

Summary:

Add new section "Known Issues and Future Development"
