[Original discussion thread follows]

Currently the page says, "The header section is everything before the first record (line) beginning with MODEL or ATOM."
However, this doesn't seem to hold in the case of `4dqo`.

The transition under discussion in 4dqo:

Should there at least be a footnote that there are some other possibilities?
Or add qualifier of `Typically,`?
Or change to after the `CRYST1`/`ORIGX`/`SCALE` section?

Resolved: After this was posted, the article was edited to include that `HETATM` can signal the start of coordinate record section.
