           Summary: @scheme attribute conflicts with Dublin Core encoding
                    scheme declarations
           Product: HTML WG
           Version: unspecified
          Platform: PC
        OS/Version: Windows XP
            Status: NEW

         Component: HTML5 spec (editor: Ian Hickson)

"The @scheme attribute of the meta element has been made obsolete and 'must not
be used by authors'" (Source:
http://efoundations.typepad.com/efoundations/2010/02/html5-metadata-and-dublin-core.html).
The HTML5 specification states that @scheme must only be declared once per
page, for character encoding. This poses a problem for those using the Dublin
Core specification for metadata in HTML5, in which encoding schemes for syntax
and vocabulary must be declared, per property as appropriate. Examples:

<meta name="dcterms.modified" scheme="W3CDTF" content="2011-03-22" />
<meta name="dcterms.issued" scheme="W3CDTF" content="2010-03-15" />
<meta name="dcterms.language" scheme="ISO639-2" content="eng" />

>From what I can tell from the HTML5 spec, this has not changed. Nor has it
changed in the W3Schools HTML5 online course:
http://www.w3schools.com/html5/tag_meta.asp

The Government of Canada has opted to use the "title" attribute in place of the
scheme attribute to declare encoding schemes, on an interim basis, as part of
the Web Experience Template. A more permanent way to declare encoding schemes
is desirable.
