DocBook NG and <biblioref>

Hi,

I was just wondering that DocBook NG (Cacha蓷 Release) supports 
<biblioref> but does not allow it inside <citation>?

Isn't it right, that <biblioref> should or can be wrapped by a 
<citation>, especially if additional text belongs to the citation or 
several related <biblioref> should be grouped?

PS: Is the docbook-list the right place to discuss DocBook NG?

Regards,
Oliver
