Just backend with capital B and I see no further issues.

there's another reference of this https://github.com/pytorch/executorch/blob/53c1a77166c6478ad30b0e1c0e2c4f5247693e6a/docs/source/embedded-nxp.md?plain=1

Thanks, fixed.

In the XNNPACK files I see both, there is capital Backend in "XNNPACK Backend" at least in headings. What I meant is to unify it, as we have strings "NXP Backend" as well as "NXP backend". That is just a cosmetic issue. As it is a backend name, I think both words should be capitalized as it is a general rule in English. XNNPACK docs can also have mistakes.

EDIT: I have looked on other backends and they are mostly inconsistent too. It should be one or the other, but always capitalized in headings.

You are right, with the consistency. Went through it and unified it to use lower case everywhere. So Neutron backend, Neutron partitioner, Neutron quantizer....
In headings using capitals for all major words, i.e. using the "Title case" (https://en.wikipedia.org/wiki/Title_case) style headings.
