standards/RIF-CS.md is not valid yaml

[hmpf]

There is a newline after "description:" on line 33 and another at line 34. Some yaml-tools:

• yamllint 1.10.0 (https://yamllint.readthedocs.io/en/stable/) which uses PyYaml
• http://www.yamllint.com/
• https://codebeautify.org/yaml-validator

among them, considers this a syntax error.
