I've authored a new topic about "Map-to-map
cascading," based on review comments from Jeff Ogden, Dave Helfinstine,
Paul Grosso, and Robert Anderson. I'll copy and paste an HTML version
below; you also can grab the file
(map-to-map-cascading-of-metadata.dita) from the archSpec subdirectory
in SVN.
Can whoever authored feature proposal #12055 review this, please?
Thanks.
--------------------
Map-to-map cascading behaviors
When a DITA map is referenced by another DITA map, by default,
certain rules apply. These rules pertain to the cascading behaviors of
attributes and metadata elements.
Cascading of attributes
When a <topicref> element references a DITA map,
the referencing map sets certain attributes. For example, consider the
following code snippet from test.ditamap:
<map>
<topicref="a.ditamap" format="ditamap" toc="no"/>
<topicref="b.ditamap" format="ditamap" audience="developer"/>
<topicref="c.ditamap" format="ditamap" scope="peer"/>
<topicref="d.ditamap" format="ditamap" print="no"/>
</map>
