`never` is being mis-reported as an invalid value of `speak`

[ianthedev]

For example, the following rule:

div {
    speak: never;
}

is being mis-reported as invalid (Value Error : speak never is not a speak value : never ).

According to the spec, never is a valid value of the speak property.

The specification you refer to is a Retired Note, meaning that it was never implemented, in that case, it defaults to CSS2 where 'never' is not a valid value (and even the implementation status of this part of CSS2 is not perfect).
