3. Plan 2014 & HTML 5.1
• Goal: How to get HTML5 to Rec in 2014?
– http://dev.w3.org/html5/decision-policy/html5-2014-plan.html

• Plan 2014 proposes how to get there:
– Charter timeline revisions:
• HTML 5.0 REC: 2014Q4
• Add HTML 5.1 for further feature development
– Permissive CR exit criteria to focus testing
– Modularity
• Address remaining open issues via extension
specs
• Provide opportunity for extension specs to
merge back

HTML.next - Proposed attributes
capture (proposal)
Provides a hint that by default, for an input element whose type element has the value file,
the file-picker control should be placed in a particular media capturing mode; possible
values are camera, camcorder, microphone, and filesystem.
inert (proposal)
A way to disable an entire subtree, without necessarily making the elements in that
subtree appear disabled (e.g., the way that controls behind a modal dialog are
“disabled” without appearing that way, in traditional UIs).
inputmode (notes)
Specifies what type of keyboard to use for a particular input or textarea element—for
example, to switch to displaying a keyboard optimized for typing in numbers rather than
letters, or for typing in URLs, or for auto-capitalizing; similar to the inputmode attribute
from XHTML 1.1/Basic.
download (proposal)
Indicates that the author intends an a element to be used for downloading a resource.
The attribute may have a value; the value, if any, specifies the default filename that the
author recommends for use in labeling the resource in a local file system.
ping (proposal)
Enables hyperlink auditing: when used on an a element, gives the URLs of the
resources that are interested in being notified if the user follows the hyperlink for that
element.

HTML.next - Proposed elements
content (Web Components)
“Represents an insertion point in a shadow DOM subtree. The insertion point is replaced with the
elements’ children at rendering time. The <content> element itself is never rendered.”
data (proposal)
For marking up machine-readable data.
datagrid (proposal)
Represents an interactive/sortable representation of tree, list, or tabular data in the form of rows and
cells. (Might be rendered in browsers as a column-sortable “spreadsheet view” and/or
collapsible/expandable “tree view”). <datagrid> was previously part of the HTML draft, but was dropped
in 2008.
decorator (Web Components)
“Defines a new decorator. Typically, you would also give it an id attribute to make it addressable from
CSS.”
element (Web Components)
“Defines a new custom element.”
intent (Web Intents)
Represents an intent registration.
menuitem (Mozilla proposal)
Represents a command in a menu in a Web application.
reco (Web Speech)
Represents a speech-input (speech recognition) control in a user interface.
shadow (Web Components)
“Specifies an insertion point, where the next-oldest shadow DOM subtree in element’s list of shadow
DOM subtrees is rendered. The <shadow> element itself is never rendered.”
template (Web Components)
“Defines an inert chunk of DOM that can then be used for creating DOM instances in an unknown
parsing context.”
tts (Web Speech)
Represents an audio stream comprised of synthesized speech output (text to speech). DOM interface
inherits from HTMLMediaElement (that is, the DOM interface for the HTML <audio> and <video
elements). http://www.w3.org/html/wg/next/markup/

• Obstruction (Mobile Web)
– Performance, Offline
– Device Capability, Monetization

24

Security Model?
• Some suggestions from John Lyle, Oxford University
– Install before execute
– Signed manifest
– Restrictions on external sources and use of secure
connections
– Least privilege access control like native app platforms
– Interoperable access control through policies or capability
tokens
– Hooks for monitoring system application activity
– Restrictions on inline JavaScript and dangerous functions
such as eval.
– Isolation expectations, e.g. sandboxed storage & inter
app communication
– Application lifecycle – update, uninstall, revocation of
privileges
– Application provenance, e.g. app store certification
– User interface guarantees, e.g. to limit clickjacking
– Fingerprinting, linkability and privacy considerations

Firefox OS
Firefox OS is a HTML 5 web-based browser, which sits on top of
Android kernals, with all the features on handsets basically being
accessed through a browser – similar to Google's Chrome OS.
