Re: [dita] Filtering with taxonomy relationships: new proposal for DITA 1.3

[Michael Priestley <mpriestl@ca.ibm.com>]

Note from last week's DITA TC discussion:

- the ditaval should get an optional
element that references the taxonomy to use; when the element is absent,
then the ditaval values are interpreted literally, without recourse to
a taxonomy to find subordinate values.

   [dita] Filtering
with taxonomy relationships: new proposal for DITA 1.3

We already have a number of proposals
on the books for 1.3 related to filters, including some that mention a
relationship with a subjectscheme map, but none seem to make explicit the
following requirement: 

- a ditaval and taxonomy should be applicable together such that if the
ditaval excludes a value that exists in the taxonomy, and document instances
contain values that are descendants of that value in the taxonomy, then
the document instances should be filtered just as if they referenced the
ancestor value instead of the descendant values. 

Example: 

a taxonomy declares "fruit" as a parent of "apple"
and "orange" 
content markup has metadata for "apple, "orange"
ditaval excludes "fruit" 
therefore content marked up with "apple" or "orange"
should be excluded, in addition to content marked up with "fruit"
