Unfortunately it seems that underscores, though no-longer invalid are
not without their problems either, at least according to Eric Meyer
(author of a number of CSS books):

http://devedge-temp.mozilla.org/viewsource/2001/css-underscores/

Though this page is old, and the browsers listed are largely
deprecated... I don't know what modern browser support is like for
underscores... I'm guessing it's pretty good and the point is largely
moot.

As far as I can see there are three options.

1) Use underscores (against the above advice) (practically probably
not a huge issue) e.g. outline-container-1_1
2) Overload the use of hyphens to be for both spaces and .'s...  e.g
outline-container-1-1
3) Stop using hyphens for spaces and switch to camel case convention,
freeing hyphens to be substitutes for .'s e.g. outlineContainer1-1.
This option seems like the best design, though it completely blows
backwards compatability away so is probably a non-starter.  Leaving us
with 1) or 2).

Personally I think *if* underscores aren't a problem for modern
browsers, ie8, firefox 3.5+, recent opera's safari and chrome we use
them.
