If some people wants to use Selectors in a language with a different 
syntax than CSS's, it's up to them to adapt the notation. And if that 
requires different escapes (or different white space, different 
comments, etc.), that's fine by me. But we, the CSS WG, don't define 
any such syntaxes.

Media Queries is different. We explicitly define how Media Queries are 
to be used in certain HTML and XML constructs and thus we have to 
define the syntax in those contexts.

I neither want to require support for backslash escapes in HTML and XML, 
nor for ampersand escapes in CSS. That implies it is possible to 
construct expressions that cannot be cut-and-pasted with a simple text 
editor, but I consider cut and paste a nice feature, not an absolute 
requirement. And in practice I don't expect to see many escapes in 
media queries anyway.
