CSS path() gives error when used for clip-path

[samhed]

The following correct CSS was taken from MDN:s example:

#mydiv {
    clip-path: path('M 0 200 L 0,75 A 5,5 0,0,1 150,75 L 200 200 z');
}

https://developer.mozilla.org/en-US/docs/Web/CSS/clip-path

The validator incorrectly gives this error:

Error: clip-path: path('M 0 200 L 0,75 A 5,5 0,0,1 150,75 L 200 200 z') is not a clip-path value.

At line 2, column 68

75 L 200 200 z');↩}↩</style>

Current version of clit-path is outdated, so it's missing some of the more modern basic shapes like path()
