String data with nonprintable ASCII characters

CR #419448

Description: Testing a message definition parser with string data may result in the following error message:

Cannot display results
Parse succeeded, but cannot display results.  Invalid XML document.

This error indicates that the test data contains ASCII non-printable characters that are not supported by the String data type for this release.

Workaround: If your message definition must be able to parse ASCII non-printable characters, change the datatype of the appropriate field from String to Binary.
