# Example: Polyethylene Glycol 3350 (PEG 3350) — a homopolymer of ethylene
#     oxide with number-average molecular weight ~3350 Da. Demonstrates the new
#     SubstanceDefinition polymer backbones added for FHIR-57660: .polymer.class,
#     .geometry, .monomerSet.startingMaterial, .repeat.repeatUnit with degree
#     of polymerisation. Adapted from ISO 11238 Implementation Guide polymer
#     example for PEG 3350.
