If one <<geometry-box>> value and the ''no-clip'' keyword are present then <<geometry-box>> sets 'mask-origin' and ''no-clip'' sets 'mask-clip' to that value.
If one <<coord-box>> value and the ''no-clip'' keyword are present then <<coord-box>> sets 'mask-origin' and ''no-clip'' sets 'mask-clip' to that value.

If one <<geometry-box>> value and no ''no-clip'' keyword are present then <<geometry-box>> sets both 'mask-origin' and 'mask-clip' to that value.
If one <<coord-box>> value and no ''no-clip'' keyword are present then <<coord-box>> sets both 'mask-origin' and 'mask-clip' to that value.

If two <<geometry-box>> values are present, then the first sets 'mask-origin' and the second 'mask-clip'.
If two <<coord-box>> values are present, then the first sets 'mask-origin' and the second 'mask-clip'.

The <a>used value</a> of the properties 'mask-repeat', 'mask-position', 'mask-clip', 'mask-origin' and 'mask-size' must have no effect if <<mask-reference>> references a <a element>mask</a> element. In this case the element defines position, sizing and clipping of the <a>mask layer image</a>.
