HTML Form attributes

Hi all,

at the last Doc Sprint in Zurich I started working on HTML Form attributes
and found out that there seems to be a lack of consistency in WebPlatform's
URL structure for HTML attribute pages.

Here are some examples:

   1. the "value" attribute has no general page
html/attributes/value<http://docs.webplatform.org/wiki/html/attributes/value>
and
   has a page for each element it applies:
   html/attributes/value_(input_elements<http://docs.webplatform.org/wiki/html/attributes/value_%28input_elements%29>
   ), html/attributes/value_(textarea_element<http://docs.webplatform.org/wiki/html/attributes/value_%28textarea_element%29>
   ), html/attributes/value_(button_element<http://docs.webplatform.org/wiki/html/attributes/value_%28button_element%29>
   ), html/attributes/value_(HTMLProgressElement<http://docs.webplatform.org/wiki/html/attributes/value_%28HTMLProgressElement%29>
   ), html/attributes/value_(param_element<http://docs.webplatform.org/wiki/html/attributes/value_%28param_element%29>
   ), html/attributes/value_(li_element<http://docs.webplatform.org/wiki/html/attributes/value_%28li_element%29>).
   Moreover, using the WP search tool there's no results matching the query
   "value" <http://docs.webplatform.org/w/index.php?search=value>.

   2. the "type" attribute page for the HTML Input element has the
   following (different) structure:
html/elements/input/type<http://docs.webplatform.org/wiki/html/elements/input/type>.
   It's located in the "elements" subtree and contains a list of the possible
   values of the "type" attribute: each item of the list links to a page with
   a URL structure like following:
html/elements/input/type/button<http://docs.webplatform.org/wiki/html/elements/input/type/button>
   , html/elements/input/type/checkbox<http://docs.webplatform.org/wiki/html/elements/input/type/checkbox>
   , html/elements/input/type/color<http://docs.webplatform.org/wiki/html/elements/input/type/color>
   , html/elements/input/type/date<http://docs.webplatform.org/wiki/html/elements/input/type/date>
    etc.

   3. the "type" attribute is defined also for other elements, but in the
   "attributes" subtree:
html/attributes/type_(button_element)<http://docs.webplatform.org/wiki/html/attributes/type_(button_element)>
   , html/attributes/type_(param_element)<http://docs.webplatform.org/wiki/html/attributes/type_(param_element)>
   , html/attributes/type_(script_element)<http://docs.webplatform.org/wiki/html/attributes/type_(script_element)>
   , html/attributes/type_(select_element)<http://docs.webplatform.org/wiki/html/attributes/type_(select_element)>
   , html/attributes/type_(textarea_element)<http://docs.webplatform.org/wiki/html/attributes/type_(textarea_element)>
   , html/attributes/type_(ul,li,ol_elements)<http://docs.webplatform.org/wiki/html/attributes/type_(ul,li,ol_elements)>
   , html/attributes/type_type_(a,_link,_embed)<http://docs.webplatform.org/wiki/html/attributes/type_type_(a,_link,_embed)>.
   (For some of these elements the "type" attribute doesn't exist in W3C
   specifications and should be deleted)

Regarding the "type" attribute, together with Chris concluded that they
should all be covered on the
html/attributes/type<http://docs.webplatform.org/wiki/html/attributes/type>
page,
so I flagged every subpage of
html/elements/input/type<http://docs.webplatform.org/wiki/html/elements/input/type>
as
Merge Candidates with the [[html/attributes/type]] page, moved all relevant
information to the page
html/attributes/type<http://docs.webplatform.org/wiki/html/attributes/type>
and
added examples.

Now, I see 2 problems in the page
html/attributes/type<http://docs.webplatform.org/wiki/html/attributes/type>
:

1) the "Applies to" entry refers to N elements, but Media Wiki doesn't
provide a way to let an attribute refer to more than 1 element (or at least
I don't know how to do that)

2) there's no way to specify the compatibility related to a specific value
of an input type (e.g. input type="date"). It was possible for
html/elements/input/type<http://docs.webplatform.org/wiki/html/elements/input/type>
 pages.

Any thoughts?
