I suggest webmaster aliases for server-wide responsability and
a typed link for authorship of any given document.   Many
servers provide stuff from many areas, one person is not
responsible for everything.  Our local mainframe doc system
has a function key dedicated to "who is responsible for the runnish  
on my screen?!" function.   This is important for up-to-date info,

I see this as one good use for a link type.  Something I have
wondered about a lot is a namespace for people in the URL scheme.
You can even find something about them using SMTP if they
are on the internet.
 <A HREF="" TYPE="author">tim</A>

Following the link would give options of mailing the person.

Any objections?

You mean http2 or html2?

I think we are allowed to let lines cross.  Just than minimising the
number of crossings (the "badness") is almose certainly np complete
But in fact a tree will probably be less confusing for people.

I like history trees like

     DDDDDD *

wheer * indicates that the links from that node are listed at a same  
or higher level in the tree.  (You could give  line number  
cross-refernece or a link to the listing).  This is gives the real  
user the comforting illusion that (s)he is playing with a tree, which  
people seem to find easier to remember than a web.

Where do we find the HyTime folk's thinking online?
