The mechanism for communicating issues (T189488) allows to surface errors and warnings of different kinds. Some of these issues refer to a specific section of the document (paragraph or title), others are general for the whole document or it may not be possible to determine the relevant part of the document.
Currently the issue system supports only issues attached to the section, and the system needs to be updated in order to support issues that are not attached to a specific part (e.g., T192144).
