Data items in the DATABASE_RELATED category record entries in
databases that describe the same or related data. Databases wishing
to insert their own canonical codes when archiving and delivering
data blocks should use items from the DATABASE category.
Example:
The loop relates a specific instance of a theophylline crystal structure
to corresponding entries in the COD and CSD crystallographic databases
as well as to the general description of the theophylline compound in the
CAS registry.
Based on the structure of anhydrous theophylline published by
Ebisuzaki, Y. et al. (1997). Acta Cryst. C53, 777-779.
