Can you explain why <mark> would be better suited in the example cases as stated in this section? I do not see that.

<div class="example">
 Note that the examples above, and even more the following
  
 <xmp>
  <abbr>HTML</abbr> stands for <u>H</u>yper<u>t</u>ext <u>M</u>arkup <u>L</u>anguage.
 </xmp>

 could and probably should be written

 <xmp>
  <abbr>HTML</abbr> stands for <mark>H</mark>yper<mark>t</mark>ext <mark>M</mark>arkup <mark>L</mark>anguage.
 </xmp>
</div>

As for the wording, “probably should be” does not communicate the confidence I’d expect from a standard.

I think it’s fine to give alternatives when alternatives are equally valid.

In general, if one alternative is clearly preferred, I would just give an example for the preferred version.

In some cases it may be helpful to provide the less preferred version too in contrast to the preferred version in order to explain a point. We would need to add an explanation if this is the case here.

I think that if we add examples, we should definitely include an example that shows the preferred use first. Adding multiple examples and then saying that neither example shows how HTML should be done best is not helpful.

I think the inclusion of these examples is confusing. I've never seen Chinese names being regularly underlined. I would remove this entire line.

Here’s a Wikipedia article about it: https://en.wikipedia.org/wiki/Proper_name_mark. Would be great to have input from China on this / gather data from chinese websites.

I don't understand this sentence. It seems to end in the middle.

Why should it probably be written this way?

I think, on reflection, because I was tired more than anything. I'll strip this bit out, and wait until we get some clarity in #1247 before playing with it again.
