[css-content][css-pseudo] alt missing from generated content module? moved?

Example 21 and 22 in the "Automatic Counters and numbering section"


...reference the "alt" property that was previously defined in this spec. 

Will someone point me to the new location of that property definition? 

I could not find it in Pseudos either.
