I'd wordsmith that a bit:

  This Task Force believes that while complete alignment between the
  HTML and XML families may not be achievable, there are nevertheless
  areas in which cross-pollination between those two stacks could help
  improve either or both. Despite the important design differences
  that exist between HTML and XML, their goals are not as divided as
  some of the stormier rhetoric suggests. There are plenty of areas of
  common experience despite significant differences in the details.

Some of these projects appeal to me more than others, but is there
a consensus on any (sub)set of them?

                                        Be seeing you,
