Adding HTML element data

Hey HTML section maintainers,

I'm planning to go through all the HTML elements with a bot and populate
the pages with all the element metadata taken directly from the HTML5
Recommendation, like categories, attributes, content model, ARIA info, and
fixes to DOM interface where that's incorrect. I have it mostly ready, the
changes will look like this (taking for example the "a" tag):


>  {{Markup_Element
> +|Categories=
> +  {{Markup_Element_Category|name=Flow content}}
> +  {{Markup_Element_Category|name=Phrasing content}}
> +  {{Markup_Element_Category|name=Interactive content}}
> +  {{Markup_Element_Category|name=Palpable content}}
> +|Contexts=Where phrasing content is expected
> +|Model=Transparent, but there must be no interactive content descendant
> +|Attributes=
> +  {{Markup_Element_Attribute_global_attributes}}
> +  {{Markup_Element_Attribute|name=href|description=Address of the
> hyperlink}}
> +  {{Markup_Element_Attribute|name=target|description=Default browsing
> context for hyperlink navigation and form submission}}
> +  {{Markup_Element_Attribute|name=download|description=Whether to
> download the resource instead of navigating to it, and its file name if so}}
> +  {{Markup_Element_Attribute|name=rel|description=Relationship between
> the document containing the hyperlink and the destination resource}}
> +  {{Markup_Element_Attribute|name=hreflang|description=Language of the
> linked resource}}
> +  {{Markup_Element_Attribute|name=type|description=Hint for the type of
> the referenced resource}}
> +|Tag_omissions=Neither tag is omissible
> +|ARIA_roles=link (default - do not set), button, checkbox, menuitem,
> menuitemcheckbox, menuitemradio, tab or treeitem
> +|ARIA_states=Global aria-* attributes, Any aria-* attributes applicable
> to the allowed roles
>  |DOM_interface=dom/HTMLAnchorElement


I'll also be creating some apparently missing pages for some elements
described in the TR: data, rb, rtc, rp, bdi, keygen, output.

Any suggestions for better ways to format this? For instance, is there a
better way to enumerate lists of categories, ARIA roles, and ARIA states?
Also considering many of these items can be conditional, e.g. "If the type
attribute is not in the Hidden state: Interactive content"

For after this is published, I can't seem to be able to edit the
Markup_Element template to make use if this data. How would I be able to do
that, or who can do that for me? With all the information, what I really
want is to calculate a list of valid parent and child elements, too, with
Semantic Mediawiki-foo.

Thanks,

Austin Wright.
