Records can be created in various ways. You can add a new
record to your application or copy an existing one. You can specialize existing rules by creating
a copy in a specific ruleset, against a different class or (in some cases) with a set of
circumstance definitions. You can copy data instances but they do not support specialization
because they are not versioned.

When searching for instances of this rule type, the system:
- Filters candidate rules based on a requestor's ruleset list of rulesets and versions
- Searches through ancestor classes in the class hierarchy for candidates when no matching rule
is found in the starting class
- Finds circumstance-qualified rules that override base rules with the same key
Time-qualified resolution features are not available for this rule type.
