Often at the start of a project some of the design criteria, limits or ranges are not known and “To Be Defined” (TBD) or “To Be Checked”/”To Be Completed” (TBC) are used in place of, or together with, the proposed values. For example, the value maybe defined but followed by (TBC).
As the project progresses, then more detail will be designed, and the requirements can be completed without these limitations.
What would be very useful is a DXL script to identify these requirements which have been annotated in this way.

This DXL script simply applies a filter for TBD or TBC for all requirements (as defined by the Object Type).
