The subject of many heated debates. The rule I like is if you have a
piece of data that is never going to contain any structure, you can
make it an attribute. I happen to use attributes a lot for numeric
values.

I would personally never use <object type="integer">20</object>, since
you might need more structure later. It is very difficult to add more
sub-elements once there is character data (DTD issue). You can use
<object type="integer"><value>20</value></object> to be more
extensible (e.g. <object type="integer"><value>20</value>
<limit><lowerbound>10</lowerbound> <upperbound>30</upperbound></limit>
<format>%2d</format></object>; who knows when we'll have structured
integers or subclassed integers like that....)
