Proposed Methods: Remove 'proposed methods' section, now covered by value-class-pattern.

	~~== Proposed Methods ==~~

	~~===As Invisible Supplementary Data===~~

	''The main content of this section — focussing just on using the [[value-excerption-pattern]] in a mark-up level hidden manner — has been moved into [[value-excerption-pattern-issues]] for easier tracking.''

	'''''These are proposals''' and therefore should be noted that they are not endorsed or supported. You should not use any of these patterns when publishing a page, but may like to [http://microformats.org/discuss get involved] to help develop these ideas.''

	~~===Proposals for more publisher-friendly mark-up for machine-data===~~

	* Extend the [[value-excerption-pattern]] to parse title attributes from empty elements with class value. Empty elements are ignored by browsers in the DOM, so won't render a tool-tip or be exposed to screen readers. Of course, it means putting an empty element into mark-up. Please post responses to this on the [[value-excerption-pattern-issues]] page.
	* Embed the data into the <code>class</code> attribute, where it will not be rendered or exposed.
	* Use a ‘<code>ufusetitle</code>’ class name to particular elements, as a processing instruction to parsers to read the <code>title</code> attribute rather than inner text. However, this adds a new concept of putting ‘parsing instructions’ into the <code>class</code> attribute, which is currently only used to extend the <em>semantics</em> of elements.
	* Break with requirements for valid HTML and adopt the RDFa <code>content</code> attribute as a means of embedding data (or another custom attribute). This results in invalid HTML.
	** Depends on what DTD you use. It would not be much work to create a DTD that added a "content" attribute to a few elements. Or simply validate against the RDFa DTD.
	* Use the title attribute on <em>any</em> HTML element for data embedding, and prefix the machine data with the string ‘<code>data:</code>’. Users exposed to the data string are given some context. This reduces the impact of the problem at the user side, and assistive technology is less likely to expose the title attribute of generic elements such as <code>span</code> as they are for <code>abbr</code>. This avoids adding empty elements to a page, but continues to expose the machine data to human users through tool-tips.
	* Repurpose the <code>input</code> element with a <code>type=hidden</code> attribute. Browsers hide this element from users completely. However, this would stretch the semantics of <code>input</code>; using an <em>input</em>, forms device for <em>output</em>.

	A final suggestion is that on a case-by-case basis, all the above documented machine-data patterns could be reworked in a human accessible, publisher compatible, internationalizable and machine-parsable manner. Previously, such solutions have not been forthcoming.

 Whilst the ''data'' ‘PT3M23S’ is an expanded form of ‘3 minutes, 23 seconds’, the text is not; ‘PT3M23S’ is nonsense to most human beings. <code>abbr</code> is an element that describes the ''text'', not the data. HTML4 has no way to mark up arbitrary data.
