Hmm, however theese are the ~ atoms, I'm not quite sure how those are
treated in the current tree, however in "my" proposal it would block
against "requirement of same package with different SLOT.  

However, since the ~ atoms are explicit and separate ( this depend tree
could as well be called :
app-text/docbook-sgml-dtd:3.0
app-text/docbook-sgml-dtd:3.1
app-text/docbook-sgml-dtd:4.0
app-text/docbook-sgml-dtd:4.1

Which, for some reason, should be supported : )   

Either by casing out appearances where multiple SLOTs are depended on by
-one- package, or by saying that ~ is special-cased due to its stricter
limitations, which would make it pass by the SLOT check.   

( no, its not an elegant solution, but it might work ;)
