/**
 * This class represents the `data` object inside the Fluid template for Content Blocks.
 *
 * Usage in Fluid
 * ==============
 *
 * To access own custom fields, use: `data.identifier`.
 * E.g.:
 * - {data.header}
 * - {data.collection_field.text_field}
 *
 * There are some special accessors, which are always available:
 * - {data.uid}
 * - {data.pid}
 * - {data.recordType}
 *
 * These special accessors are available, if the corresponding features are turned on
 * (Always true for Content Elements):
 *  - {data.languageId} (YAML: languageAware: true)
 *  - {data.systemProperties.createdAt} (YAML: trackCreationDate: true)
 *  - {data.systemProperties.lastUpdatedAt} (YAML: trackUpdateDate: true)
 *
 * These special accessors are available depending on the context:
 * - {data.computedProperties.localizedUid}
 * - {data.computedProperties.versionedUid}
