The HTML3 spec proposes "Home" for the top of some hierarchy, but
maybe "Top" would avoid clashing with the User's own home page.

This doesn't need to be specified in the document unless the browser ISN'T
in a position to work out where BACK should move to. I therefore didn't
include it in the HTML3 proposal.

> FORWARD Next (logical) document, ie down one step in the tree

Explaining the difference between FORWARD as currently implemented and
NEXT as in hypertext guided tours and MS Windows Help is tricky. FORWARD
is related to the history stack while NEXT is defined by the author.
Can anyone offer a concise and clear description for me to use?

For the next revision to the HTML3 I-D, I want to add ABSTRACT and URC
for a link to meta info in a resource catalog entry.

We could add DISCLAIMER, and perhaps something for content labeling?

> UP (and presumably DOWN?)

DOWN is handled via PREV/NEXT and BOOKMARK. Otherwise, DOWN is better
handled via hypertext links in the body of the document.


For hypertext guided tours. REL=Node and REL=Path can be used to define
implicit <LINK REL=PREVIOUS>, <LINK REL=NEXT>, as per Bert Bos's suggestion.

> HELP Valuable. Way to link to author-provided help.

This is intended for re-orienting users rather than amplifying the
document's topic.

> BOOKMARK See comment under HOME

BOOKMARK provides for a menu of convenience links that authors think
will be useful to readers. It doesn't provide hierarchical bookmarks
unlike Adobe's PDF.

Should we try to add support for hierarchical bookmark menus?
