+   It shall be checked if every feature requirement is linked via fulfilled_by at least to one valid architectural diagram/interface on the same level.
    This should also include requirement type checking:
 
    * If the requirement is of type "Functional" it shall be linked to architecture diagram elements.
-   * If the requirement is of type "Interface" it shall be linked to architecture interface elements. Here the level matching is feature <> logical and component <> real.
-   * If the requirement is of any other type there shall not be a link to architecture elements.
+   * If the requirement is of type "Interface" it shall be linked to architecture interface elements.
 
-   Note that the linking is done from the architecture element to the requirement as described for example in :ref:`allocate_feature_requirements`.
+   Note that the linking done via "fulfils" from the architecture element to the requirement as described for example in :ref:`allocate_feature_requirements`.
