Re #32 - Migrate to schemas * Remove unused method that was still validating by DTD * Collapse Cats schema in to one nested structure System files are failing to validate because: Problem validating against schema for WarFoundry data: XmlSchema error: Invalid start element: http://ibboard.co.uk/warfoundry/system:cat XML Line 4, Position 4. which is a <cat> tag, which should match the Cat schema definition. Removing the tags results in a different error about the end </categories> tag being unexpected because of missing content.
