# Comment; must be only thing on line.

Identifiers can be up to 32 characters long; they may
contain the characters A-Z, a-z, "_", "-" and "."

ENTITY_ID can be any one of SPECIES_ID, STAGE_ID, OBJECT_ID

Lists (1,2,3) must not contain spaces.

Strings "A\_ string." must not contain spaces. Use the "\_"
escape sequence.
