Type analysis of ARIA attributes

This list skips those that are numeric (already done by Domenic) or element-reflecting (should be good, apart from the naming).

role: token list

* should use DOMString (not DOMString?)

ariaAtomic: (missing), "true", "false"

* should be an enumerated attribute with no missing or invalid value default, limited to only known values
* can continue to use DOMString? in that case
* confusingly says "false" is the default, despite that not really being the case

ariaAutoComplete: "inline", "list", "both", "none" (default)

* should be an enumerated attribute with a missing value default and invalid value default ("none"), limited to only known values
* should use DOMString as missing is equivalent to "none"
* should have been named ariaAutocomplete as autocomplete is a single word per HTML

ariaBrailleLabel, ariaBrailleRoleDescription: string

* these are not reflected at the moment, why?
* should use DOMString

ariaBusy: "true", "false" (default)

* see ariaAutoComplete, only difference is the values

ariaChecked: "false", "mixed", "true", "undefined" (default)

* see ariaAutoComplete, only difference is the values

ariaColIndexText: string

* should use DOMString

ariaCurrent: complex enumerated attribute

* should be an enumerated attribute with a missing value default and invalid value default, limited to only known values
* also requires certain values to map to other values, e.g., "undefined" is "false"
* should use DOMString

ariaDescription: string

* should use DOMString

ariaDisabled: (missing), "false", "true"

* see ariaAtomic
* "false" cannot be the default here as "true" inherits

ariaDropEffect

* skipped as it's deprecated

ariaExpanded: "false", "true", "undefined" (default)

* looks like it should be an enumerated attribute with a missing value default and invalid value default ("undefined"), limited to only known values
* looks like it should use DOMString therefore

ariaHasPopup: complex enumerated attribute

* see ariaCurrent

ariaHidden: "false", "true", "undefined" (default)

* see ariaExpanded

ariaInvalid: complex enumerated attribute

* see ariaCurrent

ariaKeyShortcuts, ariaLabel: string

* should use DOMString

ariaLive: "assertive", "off" (default), "polite"

* see ariaExpanded

To be finished once there's some feedback on the general idea.
