"scheme" attribute of META element

In section 4.2.5 of the HTML 5.0 draft, please reinstate the "scheme"
attribute of the META element.

The XHTML/XHTML implementation of the Dublin Core metadata standard
makes use of the "scheme" attribute.  For instance, 

		<link rel="schema.DC"
href="http://purl.org/DC/elements/1.1/" /> 
		<link rel="schema.DCTERMS"
href="http://purl.org/DC/TERMS/" />

		<meta name="DC.subject.classification"
scheme="DCTERMS.LCSH" content="United States. Congress" />
		<meta name="DC.subject.classification"
scheme="DCTERMS.LCC" content="JK1021" />
		<meta name="DC.subject.classification"
scheme="DCTERMS.DDC" content="328" />

identifies a document as falling under the Library of Congress Subject
Heading "United States. Congress", with a Library of Congress
Classification Number of "JK1021", and a Dewey Decimal Classification
Number of "328".

At the U.S. House of Representatives, we have been using Dublin Core
since 2005 as part of our efforts to promote web standards compliance.
