RE: [css-variables] Last call comments

TLDR: Why should attr(data-xyz) be called an Attribute REFERENCE while var(xyz) should be called a variable? Both are the same concept, and this is not the concept of variable but the one of a reference. This is why I keep my proposal to use the Property Reference name.

Wait, it's still about compile-time vs runtime. It's not because your language has a Static Single Assignment that it's a different version of variables. Variables in this context are created at some point (or a considered global) and can't change of value therafter, it doesn't mean anything about the variable definition.

The second thing is: the variable is the memory box, not the reference to a memory box. This is called a pointer, and, in the case you want live updating like in the CSS case, a dynamic reference or a data binding.

Why should attr(data-xyz) be called an Attribute REFERENCE while var(xyz) should be called a variable? Both are the same concept, and this is not the concept of variable but the one of a reference. All this is a non-sense.
