This case-sensitive code system http://hl7.org/fhir/questionnaire-derivationType defines the following codes in a Is-A hierarchy:

Lvl	Code	Display	Definition
1	extends	extends	Indicates this Questionnaire includes all of the items and permitted answers present in the target Questionnaire, however it also adds additional items and/or answers. A QuestionnaireResponse against the referenced Questionnaire should be valid against the referencing Questionnaire. However, a QuestionnaireResponse against the referencing Questionnaire might not be valid against the referenced Questionnaire.
1	compliesWith	complies with	Indicates this Questionnaire is derived in a manner that ensures that QuestionnaireResponses completed against this form will also be valid against the referenced questionnaire. To be a valid constraint, linkId, item types, and item order must align and all required items and answers must be included. However, cardinality can be tightened and answers can be restricted. If a Questionnaire complies with a parent Questionnaire, that does not mean that the derived Questionnaire is considered to have the same validity as the parent Questionnaire.
2	validAgainst	valid against	The changes made are ones specifically contemplated in the design of the base Questionnaire such that it is still considered 'validated' for use. E.g. questions removed were marked as 'optionalDisplay' in the original, or language translation performed has been confirmed to not change the interpretation of or likelihood of certain answers.
1	inspiredBy	inspired by	Indicates that some portion of the content of this Questionnaire was drawn from the referenced Questionnaire. Responses created against this Questionnaire have no expectation of being valid against the referenced Questionnaire. linkIds, question text, answer choices, etc. may all vary and items may have been added or removed.
