If I reuse the same topic in multiple bookmaps, and those bookmaps have a difference in profiling attributes (let's say, @product), then I can customize the topic for each bookmap:
<p product="p1">This is customized for Product P1.</p>
<p product="p2">This is customized for Product P2.</p>
But let's say I reuse a topic multiple times in the *same book*:
<topicref href="mytopic.dita" keys="my1"/>
<topicref href="mytopic.dita" keys="my2"/>
What mechanisms are available to customize each instance of that topic in the same book?
Is there a way to push a profiling attribute down into a referenced topic from the map?
