B.1.2 Introduction

Domain-specific compressors can be assigned on a per-node basis. This registry defines the mapping of node and encoding values to specific techniques. Negative encoding values are reserved for private compressors. The interpretation of such compressors is implementation dependent.

The node compressor mappings specified by this part of ISO/IEC 19776 are listed in Table B.2:
