Yes, I guess you could refine is-a as well. Finding good atoms in this
world is difficult.

A very orthodox, minimalistic approach to XTM and Topic Maps (which

type in the same way as some programming languages often do not
themselves include any data type.

This would have reduced the practicality a bit, though.
