mmm, if you really look at it, things are mudded because you forget that
<table> is an object having a field "rows", which is  a list of elements of
"type" <tr>, and that <tr> is an object having a field named "cells" having a
list of <td>s as values.

Now, replace the word "field" by "attributes" and you see that contents is
actually a kind of attribute, with its real name omitted and implicit
(actually, explicited somewhat in the DTD.

Everything is confused in XML because everything is of type "text", that you
mix n match everywhere.

For me, your exemple *should* be written in an ideal XML 2:

<table border="2" cellpadding="50"
  rows=	 <tr cells=<td contents="One"/><td contents="Two"/>/>
         <tr cells=<td colspan="2"contents="Three"/>/>
