My current thought is something like:

@custom-media "small" (max-width: 20em);
@custom-media "large" (min-width: 40em);
<link rel=stylesheet media="('small')" >
<link rel=stylesheet media="('small')" >

Note the use of quotes - using strings as the name avoids any possible
collision with future MQs we define.

Another possibility would be to use a reserved prefix, like Custom
Properties use.  It seems a little weird to use "var-", but honestly
it might be easiest to learn like that.
