while in the header of a document the link tag could be explicit, e.g.:
<LINK ROLE="Next" HREF=""http://.../NEJM09011994/">
with the explicit LINK elements in the header considered static
structure of the document and the GROUP encapsulated LINK elements
considered as dynamic and not part of the document (ala HyTime ILINK).
We have modified Mosaic to have a set of buttons for the static LINK
elements and a dynamic menu for the dynamic LINK elements, with the
buttons greyed for non-specified LINKs and the menu built on the
encapsulating GROUP elements.
Our canonical example is a set of articles that have some static
structure, represented in the static LINK elements, as well as some
dynamic structure, e.g. a list of "hits" from a DB search. This would
allow the user to read the article using the static LINKs and also go to
the next, previous, etc... articles in the hit list.
Our implementation of EMBED, as documented in our paper "Integrated
Control of Distributed Volume Visualization Through the World-Wide-Web,"
to appear in the proceedings of IEEE Visualization 1994, is as follows:
<!ELEMENT EMBED EMTPY>
HREF %URL %REQUIRED
TYPE CDATA %REQUIRED
WIDTH NUMBER %REQUIRED
HEIGHT NUMBER %REQUIRED>
The EMBED element arranges for the execution of a external application,
based on the MIME content-type, to take the data specified in the HREF
and perform its actions appropriately. The browser allocates a window
in the document for the application's output (400x400 requested) and
maintains a dialog w/ the external application, informing it of state
changes (e.g. change page).
I would like to discuss more with you how we can work together to get
all three ELEMENTS defined and implemented for the next specification.

Its too late to put these into the 2.0 spec, particularly as the spec aims to rationalize the de facto situation *NOT* future enhancements. However, I am the editor for the 3.0 draft spec which the group will start working on once the 2.0 spec is signed off. The plan is to base the HTML 3.0 spec largely on HTML+, and I am currently working with CERN to build a public domain X11 browser for HTML+/HTML 3.0 to support this process. This browser will be made available later this Fall.
The EMBED and GROUP elements refer to an older version of the HTML+ spec. I backed off <embed> for technical reasons and now am following a path which generalises inlined material by using OLE/OpenDoc style application embedding in HTML documents. Can you tell me more about how you are using these elements in your implementation?
You can read an overview of the latest state of the HTML+ spec, as presented at WWW'94 in:
