[jordanpadams]

💪 Motivation

...so that I can more easily configure validate using common XML tools (e.g. Oxygen)

📖 Additional Details

⚖️ Acceptance Criteria

Given a valid harvest config file with a harvest namespace / schema specified
When I perform validation through an XML validator (e.g. Oxygen)
Then I expect the config to validate successfully and be utilized by harvest
