Mention is created every time someone uses "#<number>" (e.g. "#123") in the text of issue or in the comment, where number is a sequential number of issue or pull request [2]. When comment is published in issue A which mentions issue B, there is a pseudo-comment added to B, and subscribers of B receive email notification.

>>>   * "#<number>" is not a safe reference format. Sometimes users' comments may have other data in "#<number>" format with a different meaning than references to GitHub issues. For example, may the force be with you if someone pastes gdb or lldb backtrace into comment without escaping it into markdown raw text block (```). Also, GitHub parses mentions in git commit messages, so care must be taken to avoid any occurrences of "#<number>" with a meaning different from reference to issue number.

> As I've mentioned above, for this particular case you could create a milestone "Implement v1 shadow DOM API" and add all subtasks to it. Then you have a list of dependencies in one place, with ability to see only unresolved once, and with a nice progress bar. But you may find this approach a bit lame, because milestone itself is not a proper task, it has nothing else but title, description, and due date. Also, it's probably wrong to call this entity a milestone.

Also it doesn't allow to create dependency tree with depth > 1, as children of milestone cannot be milestones themselves.
