One question would be to clarify what you intend to support as a "pattern". Do you intend to limit things to bitmap/raster tiles, or do you want to extend it to fully cover vectors, procedural code, etc?

That was one of the first issues I spotted when I was looking into this a while back. For one simple example, a "pattern" in SVG is allowed to be anything (vectors, images, gradients, transforms, filters) that will be repeated in a rectangular tiling. http://www.w3.org/TR/SVG/pservers.html#Patterns
