On a more practical than ideological note, selecting the parent and 
grouping the children often greatly helps avoid duplicated content. This 
is so because you cannot just do an apply-templates over all nodes 
within p. You need to be careful which node isn't replicated because it 
is already considered by the following-sibling grouping. On the other 
hand, you cannot just restrict yourself to processing the first 
ph[@outputclass] child because you need to process its 
preceding-siblings, too.
