For each qualifier defined in the application’s schema, an entry will be defined in the SCHEMA.QUAL dictionary for the qualifier’s API code.

Qualifiers are not defined with object references in the JavaScript API. You should not rely on the values of these constants, and they may vary between applications even if the qualifier is defined in exactly the same way. Always use the symbolic names.

For example, QUAL["dc:qualifier:alternative"] is the built in Alternative qualifier.

To make your code easier to read, you should use plugin local schema dictionaries.

Null qualifier

QUAL["std:qualifier:null"] is a special qualifier value, which means no qualifier applies to this value.
