'eol' documentation confusion

Upon inspection of the gitattributes documentation page here: https://git-scm.com/docs/gitattributes

When comparing the documentation for 'text' with 'eol', I see the following missing explanations for 'eol':

* eol
* -eol

Maybe the fact that these are missing means they are not valid to use. There is also the issue that `text` usually controls EOL anyway. Is there ever any reason to set eol in a way differently than explained in the documentation (that is, `eol=lf` or `eol=crlf`)?

For example, what if you want a file to be treated as text BUT you do not want it to perform EOL normalization at all. Could you do this?

    foo.txt text -eol

Just at first glance, this to me would mean line endings on checkin and checkout are not touched (CRLF could be checked in). Is this possible?

What about setting `eol` but not `text`?

Honestly it seems like `eol` is just a supplementary setting for `text` and was never intended to be used in ways that are undocumented. Some explanation to help uncloud this would help, or maybe I missed something in the documentation that explains this.
