Importing DDL that contains unsupported syntax produces the following "Import Messages":

• 2 instances of a DDL statement of type [ddl:ddlProblem] were found, but cannot be processed

This message doesn't give any indication as to which statement (s) are the issue. And didn't find any message(s) in the .log file either. It would be better if "ddl:ddlProblem" was replaced with the first "x" number of characters from the statement that was identified as a problem.
