Epic6: What controls the "completeness check," and how can I override it?
We're starting to create Schematron files to validate our XML content, now that support for them has been introduced in Arbortext Editor 6.
However, when writers on the team use the "Check Completeness" feature, they receive a list of warnings that are completely safe, in addition to legitimate Schematron issues. For example:
DITA Markup ProblemsWARNING:
"foo.xml" is missing an xml:lang attribute on the root element.
DITA Reference ProblemsWARNING:
Unusual value "new-window:PDF" specified for type attribute on xref element in "foo.xml".
WARNING: External/Peer reference to "bar.pdf" on xref element in "foo.xml" is not represented in a correct format
While Arbortext may think that every root element, for example, needs an xml:lang attribute defined, we put ours in during build time in order to support multiple languages. And new-window:PDF is also an attribute used for special purposes for the build.
Is there some way I can override or "block" checks that I know are not necessary? At the least I'm looking for just running Schematron against the file, but what would be best is Schematron + well-formedness / context rules.
