The standard link style is solid underline.
However, G183 says If there are not a large number of links in the block of text, underlines are recommended for links in blocks of text..
I think another link style not visually distracting is needed in the case of a large number of links such as wiki pages.

The various examples provided in G182 (blue bold text, red italic text) may not actually be recognized by users as links.
This is because website viewers do not have enough experience to recognize not solid lines as links.
So, I thought that providing another one new technique might have some hope of creating a de facto standard like solid lines.

I have a similar issue for WikiMedia.
Reading the link below may help you imagine about this issue.
