/**
 * S-101 data model types.
 *
 * S-101 is part of the S-100 framework and uses ISO 8211 encoding.
 * Key differences from S-57:
 * - Feature types use string codes (e.g. "DepthArea") mapped to numeric IDs via catalogue
 * - Complex (nested) attributes alongside simple ones
 * - Information records (metadata that features reference)
 * - Curve geometry types (arcs, composite curves)
 * - Feature associations (feature-to-feature links)
