Example 22 says if you want a HR in your list use a different bullet.
If you want a horizontal rule in a list item, use a different bullet:
- Foo
-
-
- *
- *
-
Example 16 states:
However, no other characters may occur at the end or the beginning:
_ _ _ _ a
a------
_ _ _ _ a
a------
This is quite confusing as it seems that “No other characters” should either be specified as no other “non list” characters, OR example 22 appears that it should have generated
Following onto this;
It is required that all of the non-space characters be the same. So, this is not a horizontal rule:
Example 17
-
However is * — * a horizontal rule? since there are 3 contiguous?
I would expect based on example 17 it would be

But to be honest I’m not sure what the result will be based on the spec.
