As far as I see, you just can't do that. You will have to use '_'
instead, and then ?replace('_', '-') it where you print it. /-:

Yeah... it should be improved in the parser. Except, it can't be done
in a backward-compatible way. <@foo 'data-bar'=1 /> means
<@foo 'data-bar' == 1 />, since for whatever reason '=' is an alias to
'=='.

Cloud computing makes use of virtualization - but cloud computing 
also focuses on allowing computing to be delivered as a service.
