Ifwe don'r end up with thousands of testcases we don't have enough :)

Indeed. But for complex parts of the spec (like say, parsing) it is a 
non-trivial amount of effort to enumerate all the 
parts of the specification that a particular test depends on. Saying 
that something tests "" isn't really useful; that section of the 
specification has a huge number of possible behaviours depending on the 
token being processed and the prior state of the tree. Understanding 
whether you have complete coverage or not relies on knowing that, for 

<!doctype html><table>x</table>

has quite different behaviour to:

<!doctype html><table> </table>

Which you can only learn by reading the "Anything else" clause in On the other hand, getting the right resulting tree depends on 
getting a huge number of other sections of the parsing spec right and, 
in particular, one might naively identify the first test as a test of alone. So it is quite unclear to me how one would add the right 
metadata to determine which sections a test covered without adding a 
full list of states that a test was expected to pass through and which 
actions it was expected to take in each.

Perhaps for the case of parsing we need a more automated approach to 
determining which tests cover which aspects of the specification?
