"Links" are key for any information system and XML is no exception ! 

Without "links" (taken in the general meaning of the word) a RDBMS would
be nothing more than a set of spreadsheets.

<advert kind="shameless">
Practical ways to express links with XML is the subject of an article I
have written for XML.com [1] and of the tutorial I will be delivering at
WWW10, XML Europe 2001 and (if my submission is accepted) XTech 2001.

Yes, that would be really great to have schema languages that let you
describe the links within and also between documents.

XML Schema languages seem to focus on single documents and this looks
also like a necessary extension !
