It's the same prose in CSS2 and CSS2.1.

Actually I found 5.2 clearer.

I was reading 'subject' in 5.10 as not including the pseudoclasses, but 
only relating to actual elements in the document tree. The description of 
'subject' doesn't help me much:
"The elements of the document tree that match a selector are called 
subjects of the selector."



5.2:
"... One pseudo-element may be appended to the last simple selector in a 
chain ..."

This clearly states that the pseudo-element comes after the simple 
selector, which is defined as including the pseudoclasses and attribute 
selectors etc. That answered my question.
