removal of "content" limiter from major changes, in an attempt to clarify one aspect of #737 without having an impact on the rest of the standard

Closes #737

[patrickhlauke]

I think/thought that based on @alastc's comment #737 (comment) this PR might still be relevant/could be reopened?

Discussion on call 2/1 got more than a bit sidetracked. See minutes.

removal of "content" limiter from major changes

My understanding is that "from major changes" refers to another PR which AG WG did not reach consensus.

This PR is intended to be editorial only, This PR removes "content of the Web Page" from the beginning of changes-of-context definition because there is a lexical contradiction with the current phrasing.

Discussion is in #737

Sorry @patrickhlauke as that was the opposite effect I was hoping for,!

On the call yesterday I was thrown by reading this PR (and Mike's terse description) before the discussion thread. Based on the live conversation (and as reflected in the minutes), I was not the only one confused. I thought by commenting here in the PR that I was helping.

Maybe need to address changes in focus, window, etc. more clearly, although mentioned later in the list below. e.g. "Major changes in content or focus"? "Major changes in the following, ..."?

@cliffbert i'm afraid that ship has sailed, after 2+ weeks of back and forth discussions (and see the whole lengthy discussion on the original topic #737 as well, and counter-proposals, and two rounds of voting in AGWG meetings, etc). i'd say this is the least bad correction that everybody could agree on...which is still better than what it was before.

Agreed: https://lists.w3.org/Archives/Public/w3c-wai-gl/2022JanMar/0095.html

NB: NOT deleting the branch until I'm sure it's in the WCAG2.1 branch as well.
