I think the comment would be more accurate as "Both the value attribute and the text content are static", right ?

Hmm, it's a bit obscure: If the attr is defined, we create an interpolation fn for it (to check if we should observe). We then skip everything related to the option text, because the value takes precedence over it. Which means, while the option value attr might not be interpolated, the option text could still be. Does that make sense?

You are right; then both wordings are inaccurate. It should be more like:
Either the value attribute exists and is static or it doesn't exists and the text content is static
(which although more accurate sounds messy anyway - so I leave it up to you :)

I think just noting that the attr value is static should be enough then. The code isn't that big, it should be relatively easy to find out what exactly happens.

This is for options added without ngOptions. Previously, an option with an interpolated value attribute would not be updated if the binding changed, i.e. the select controller would not recognize the changed option. Now the value attribute will be observed if it contains an interpolation. Closes angular#12005 Closes angular#12582

Previously, the option would only update if the fallback
(the interpolated option text) was used. Now the value attribute will
be observed if it contains an interpolation.
Closes #12005
