Following my other thread with CSSParameter and SVGParameter and the
revelation there's a SVG 1.0 and 1.1, I've discovered this issue is caused
because the stylesheet is 1.1.0, and apparently GeoServer can't handle
external SVG fills with that version yet.
I converted it to 1.0.0 and it now mostly works, but there's one problem:
One of the key elements I was using was "<Displacement>", which allows you
to offset a fill by a specified number of pixels, but this doesn't appear
to be in 1.0.0. Is there any way around this or is it simply a case of
waiting for that aspect of SLD 1.1 to be implemented into GeoServer?
Thanks,
Jonathan
