CSS selector indirection is already pretty confusing to a lot of authors, but
it has three advantages that don't apply to RDFa: errors don't cause bad data
to be generated, selectors can be written by trial and error without the use of
tools beyond a browser, and it's not a rebindable prefix mechanism.

> Sure.  RDF/XML

Not in use in any sort of wide scale, and equally bad.

> N3

Not in use in any sort of measurable scale.

> Office Open XML

Not hand-authored.

> URIs (IRIs etc)

Doesn't use a rebindable prefix mechanism.


Not in use in a way that uses a rebindable prefix mechanism.


Not in use in a way that uses a rebindable prefix mechanism.

Doesn't use rebindable prefixes that are combined with a second string to form
a third string whose value matters in a way that it could be constructed in any
arbitrary other ways.

Then I think we should not have the technology.

I think that the HTMLWG should be designing technologies for orders of
magnitude more usage than RDFa current has.
