Documenting controls

Answer:

First lets understand the differences between these documents. Normally policies define general guidelines (what must be done), while procedures are more specific (defining how to perform an activity), but it is not mandatory that your documentation is divided in such way.

Considering that, if your "policy" fulfills requirements from Annex A control A.9.4.2 this is compliant with ISO 27001 and will be acceptable for certification audit.
