  ## Remarks
  +Certain requirement sets can't be declared in this element of the manifest; they're listed in the following table. In those cases, you should do a runtime check to determine if the user's version of Office supports your target requirement set. To learn more about how to do so, see [Runtime checks for method and requirement set support](/office/dev/add-ins/develop/specify-office-hosts-and-api-requirements#runtime-checks-for-method-and-requirement-set-support).
