CODEVALIDATION_SAMPLECODE
STRING, comprising a sequence of printable characters, including lowercase and uppercase characters, with support for extended characters using the &#nnn; format. For example:
-   for space
- ° for °
- µ for µ
When a sample is requested to be created, then:
- If empty (default on deploy), then if the code of the sample, as created by the sample code syntax, contains a character not in the ABCDEFGHIJKLMNOPQRSTUVWXYZ_0123456789 character set, then the sample creation does not proceed.
- If not empty, then if the code of the sample, as created by the sample code syntax, contains a character not in the provided set of printable characters, then the sample creation does not proceed.
Typically the preference is not set at role or user level.
