to follow up on what Pawson, David said:

They are defined by their use in headers and footers.  They are
attributes, but not SGML attributes.  They are defined in the
page context in CSS.  They are not attributes in the document
language model for HTML because HTML declines to define a page
context model.  For details consult the discussion in and around

 12.3.6 Marking elements for the running headers & footers

I think that a lot of functionality will wind up deferred to the
XML generation of formats.  But right now the HC job is to try to
capture what the desired functionality is before we discuss it
with the developers of CSS.  Following that discussion, we may
have to come back in the next generation to get certain "nice to
have" upgrades.

My position is that the scope of a "document" i.e. an HTML file
is an artifact of the communications protocol and dominant
medium.  To come up with a universal WWW we need to base the
content model on a continuous web of information which is
segmented into HTML files much as print styles segment a long
document into page units.

The reason the Web is a winner is that the content is a better
fit to a web than to a tree.

As TimBL says, we don't want to lose that baby with the
bathwater as we add formatting niceties.
