##       'character', or 'end-of-file'
##   ->{name} (DOCTYPE, start tag (tagname), end tag (tagname))
    ## ISSUE: the spec need s/tagname/tag name/
##   ->{error} == 1 or 0 (DOCTYPE)
##   ->{attributes} isa HASH (start tag, end tag)
##   ->{data} (comment, character)

## Macros
##   Macros MUST be preceded by three EXCLAMATION MARKs.
##   emit ($token)
##     Emits the specified token.

## Emitted token MUST immediately be handled by the tree construction state.

## Before each step, UA MAY check to see if either one of the scripts in
## "list of scripts that will execute as soon as possible" or the first
## script in the "list of scripts that will execute asynchronously",
## has completed loading.  If one has, then it MUST be executed
## and removed from the list.
