Actually Frank had the information somewhere on his hard drive, but it was
not not well indexed<grin>

Now I've searched them down however here is the relevant documentation
relating to Links


Note in particular what the DTD says about the parameter entity LinkTypes

<!ENTITY % LinkTypes "CDATA"    -- space-separated list of link types    -->

This means that a link type can be absolutly any string we want!( no '<' or
'&' allowed though)

The specification defines the suggested types as in the URI provided by John

>types defined in HTML 4.0 is in the spec at

However, as noted by the Web Design Group

I don't know of a format. It may be a good idea to work on one, because as
the  concept of the web as a series of objects grows, I think every one in
this thread agrees  the LINK element provides a suitable way of describing

I suppose a file with a SGML type comment would be as good a way as any

<!--supplemental values for % LinkTypes

Exactly but a 'hack'


>page.  (Except--argh!--there is no NOTES or FOOTNOTES link type

I supose PREVIOUS would work as the two pages form a "collection", but its
still a 'hack' and I agree footnotes would be much better.

Actually I think that if we are using LINK to help soft ware find its way
around and understand the structure of our sites it would be better to put
Links at both ends AND be verbose. After all you define an objects methods
and properties.

Getting back to the method of defining values for I suppose the best way
would be to use SGML syntax
