Currently reads:

Consumer App actors SHALL be capable of processing resource instances containing the data elements without generating an error or causing the application to fail. In other words, Consumer App actors SHOULD be capable of displaying the data elements for human use or storing the information for other purposes.

This reads as two separate requirements rather than a restatement of a single requirement. I suggest splitting them into separate bullet points

Suggest:

Consumer App actors SHALL be capable of processing resource instances containing the data elements without generating an error or causing the application to fail.

Consumer App actors SHOULD be capable of displaying the data elements for human use or storing the information for other purposes.
