If we stay with "PT2M23S" then how are we going to deal with the title
attribute issues.
Are they to be put up with, or do we lay "PT2M23S" side by side with
the appropriate duration.

With the ABBR element it's considered to be invalid if it's empty

I consider the following to be bad
    <abbr class="duration" title="PT2M23S"></abbr>2:23

Next we have the classical abbr-include-pattern.

This has issues in that the title is not an acceptable abbreviation of
2:23. The title text must be sensible to the human viewer.
    <abbr class="duration" title="PT2M23S">2:23</abbr>

Then there's the SPAN element. This one too has issues with the title
text, in that anybody seeing it isn't likely to understand its
meaning.
    <span class="duration" title="PT2M23S">2:23</span>

It appears that when the title text is used on content, it must must
remain as a human-understandable construct.

The SPAN element however has classically been allowed to be empty, as
a placeholder for the likes of css images.
This situation can be leveraged to provide computer data, without
interfering with the content itself.

I consider the following to be less bad than the others above.
    <span class="duration" title="PT2M23S"></span>2:23

It still has a few issues, but I consider it to be better than the
others that have been available.
