RE: [dita] Clarification of conref and cascading attributes

["Jim Tivy" <jimt@bluestream.com>]

Agreed

I would think that when

<topicref id="sample"/>

or any other fragment for that matter, is the target of a conref it is taken
out of its context without its context and put into another context.
