The experimental HTML5 conformance checker throws an error when more than one
space separated value is used within a role attribute. However, the Role
Attribute Draft [1] defines
"The role attribute takes as its value one or more whitespace separated
TERMorCURIEorAbsURIs as defined in [RDFA-CORE]"
The HTML5 spec fails to specify yet that one or more values is allowed, but it
seems to be the base for conformance checker implementations. Therefore I
suggest to include the sentence above, unless it doesn't need to be specified
redundantly and it is a failure on the W3C validator to implement the Role
Attribute specification properly.
Use cases for multiple roles:
1. It would be appropriate for a horizontal main navigation to have
role="navigation menubar"
2. On flickr, headings can be edited when they receive focus. It's a heading
that should be included in the taborder via tabindex="0", but as soon as it
received focus it becomes a text input field. Therefore <h1 role="heading
textbox"> would make perfect sense as the element has the potential to be both:
Schrödinger's Heading.
