@media syntax / possible combinations

问题

I've seen some of these...:

@media print { ... }
@media screen, handheld, print, projection { ... }
@media all { ... }
@media all and (property:value) { ... }
@media screen and (property:value) { ... }
@media only screen and (property:value) { ... }
@media screen and (property:value) and (property:value) { ... }
@media screen and (property:value), tv and (property:value) { ... }

...but I'd like to know the exact syntax / all possible combinations for media queries because I'm modifying a CSS parser.

Many Thanks!
