Well, now I know what it does excatly (my testing was incomplete),
I agree that's an obscure feature. But you misread my original
bug report, which was *only* about XML comments (obviously not
all markup): "spelling doesn't work in XML comments"

Yes, apparently a missing feature (unless there's some undocumented
variable with an obscure name and documentation...).

I searched only about "XML". The user is not expected to spend
hours trying to search every variant (HTML, SGML, SVG, MathML,
etc.).
