This is a somewhat non-trivial question, due to the complexity of XML and 
HTML parsing and the side-effects these have on the corresponding DOMs, so 
instead of risking missummarising the requirements, let me just give you a 
link to the relevant part of the spec:


Let me know if that is unclear. (Note in particular that the first few 
paragraphs are the authoring conformance criteria, and that the UA 
conformacne criteria, including error handling for the case where the 
attributes have different values, are given after the first note. If you 
have the UA requirements highlighted -- the radio buttons at the top right 
of the spec to toggle this -- then the UA requirements are shaded red.)
