No, but then again, the context of a random class attribute is not
necessarily limited to the hcard itself. It is up to whoever
defines the hCard microformat to say what a given attribute means
in any given context.
Not exactly. We can add new context to HTML-defined contexts, but we
can't actually change the HTML-defined context.
HTML defines REL:
http://www.w3.org/TR/html401/struct/links.html#h-12.2
This attribute describes the relationship from the current document
to the anchor specified by the href attribute
Nothing a microformat spec says will prevent rel from applying to the
entire document. We can add more local meaning *in addition to* that
document-wide meaning, but we can't change what the HTML spec says,
which is that rel applies to the whole document. If something can't
apply to the whole document, it doesn't belong in REL.
HTML defines CLASS:
http://www.w3.org/TR/html401/struct/global.html#h-7.5.2
This attribute assigns a class name or set of class names to an
element.
Class is always local to a single element. We can add broader
meaning *in addition to* that local meaning. This is somewhat the
opposite of REL.
Peace,
Scott
