Avoid option conflicts between classs and packages
Brief outline of the enhancement
From https://github.com/latex3/fontspec/issues/501, I think it would be great if LaTeX could provide some interfaces to reduce option conflicts between classes and packages using \DeclareKeys
command.
Sometimes a class defines some key and hopes it to be used only by itself. So I think some key property .scope = local
would be very useful:
\DeclareKeys {
key .scope = local,
key .code = {foo},
}
And it is also good to provide a public command \RemoveKeyFromOptionsList
.
