ISSUE-24: Should all terms be case-sensitive in HTML5 and XHTML?

Case-sensitive terms in HTML5

Should all terms be case-sensitive in HTML5 and XHTML?

State:
CLOSED
Product:
RDFa 1.1 Core
Raised by:
Shane McCarron
Opened on:
2010-05-13
Description:
All RDFa 1.1 Processors force any prefix specified via xmlns: and @prefix to lowercase. Since comparison of terms in @rel and @rev in HTML5 are case-insensitive, should RDFa Processors force these terms to lower-case as well to ensure HTML5 and XHTML compatibility?

Related notes:

Forcing terms to lowercase would be a disaster for this use case:

<a vocab="http://purl.org/dc/terms/" rel="conformsTo" href="http://example.org/foo">Conforms to Foo</a>

We can't just lower-case any term in @rel or @rev.
