In CSS Transforms, various property values cause a stacking context to be  
established:

- "In the HTML namespace, any value other than ‘none’ for the transform"  
(how about generic XML? Isn't this rather about anything other than SVG?)
- "Any value other than ‘none’ for the transform" (this time no further  
qualification is given)
- "A value of ‘preserve-3d’ for ‘transform-style’"
- "The use of [the 'perspective'] property with any value other than  
‘none’"

However, nothing is said about the stack level of such a stacking context.  
I believe the spec needs to say that the stack level is 0 when the element  
is not positioned, similarly to what CSS Color says in the 'opacity'  
section.
