As per the specification below, it appears that &lt;input type='url' /&gt;
fields will not support the special form URL localhost, I believe this to be an
oversight as in many cases when querying the user for a url, especially in the
case of most post-form applications of this input type, localhost is a
perfectly valid response.

In example, a user is instructed to enter the information of a database to
connect to, usually the response will be in the form of schema://&lt;ipv4
addr&gt; or localhost, however, occasionally it will take the form of a url
[very likely one the user agent has encountered before].  Forcing this
application to use the type='text' field will under-utilize the information the
user-agent may be able to supply to the user.

As an aside, thank you for your time in reviewing this.  I am quite excited
about the new introductions into the html standard this offers as it may help
move web development away from reliance on obscure or arcane classes/ids.

4.10.7.1.4 URL state

The value attribute, if specified, must have a value that is a valid URL
potentially surrounded by spaces that is also an absolute URL

2.6 URLs

A URL is an absolute URL if resolving it results in the same output regardless
of what it is resolved relative to, and that output is not a failure.

An absolute URL is a hierarchical URL if, when resolved and then parsed, there
is a character immediately after the <scheme> component and it is a U+002F
SOLIDUS character (/).

An absolute URL is an authority-based URL if, when resolved and then parsed,
there are two characters immediately after the <scheme> component and they are
both U+002F SOLIDUS characters (//).

To parse a URL url into its component parts, the user agent must use the parse
an address algorithm defined by the IRI specification. [RFC3987]
