XML files are structured as trees.  Thus you cannot represent this in the
structure of XML.

You are better off having some form of element representing each of your
relations in a many to many scenario
 
You might want to look at
http://www.yy.cs.keio.ac.jp/~suzuki/project/uxf/uxf.html
which contains some DTDs for representing UML, though these use some text
matching or element contents for relations (such as source or target of state
machine transitions) which might better be represented as an XLink attribute.
