# Relational property: the mass fraction of iron in steel sheet SH-0417 does not belong to the iron alone or to the
# sheet alone, it holds between them. A concentration value specification gives it a value in mass-%.
# The identifiers and the value are invented; the classes and properties are the pattern's.
