Clarrification of @href/@keyref on <data> element

[Eliot Kimber <ekimber@rsicms.com>]

The 1.2 reference entry for <data> says for the @href attribute:

"Provides a reference to a resource. See The href attribute for detailed
information on supported values and processing implications."

However, I can't find any discussion of what it actually means to have
<data> associated with a resource.

Do we say anywhere?

If not, what is the intended implication? Is the associated resource the
metadata value?

Thanks,

Eliot
