Namespace prefixes are case-insensitive. For example, ABC and abc aren’t recognized as unique. Your namespace prefix must be globally unique across all Salesforce orgs. Salesforce automatically prepends your namespace prefix, followed by two underscores (“__”), to all unique component names in your Salesforce organization. A unique package component is one that requires a name that no other component has within Salesforce, such as custom objects, custom fields, custom links, s-controls, and validation rules.
