"2.12 <br>

Indicates that a line break should be inserted in the generated output 
by a formatting tool. It is always expressed as <br />. Multiple 
successive instances of this element do not cause blank lines to appear 
in the output, and is thus not useful.

This element appears as a child element of <td> (Section 2.56) and <th> 
(Section 2.58).

Content model: this element does not have any contents."

Question: I assume this is here because splitting the cell's content 
into multiple <t>s would create too much vertical whitespace?

Other than that:

- What is "It is always expressed as <br />" about?

- "Multiple successive instances of this element do not cause blank 
lines to appear in the output, and is thus not useful." -- maybe "are 
not useful" - or just state that they'll be ignored? What if there's 
whitespace in between, such as with "<br/> <br/>"?

Best regards, Julian
