Re: problem self-referencing using document('') to reference parameters

When using document('') you're not actually referring to the stylesheet 
itself. The document() function pulls in a new document from the network 
from the specified url, when you use the url '' that happens to resolve 
to the same url as the stylesheet. But the document will still be pulled 
down from the network (or, more likely in this case, from the cache) so 
naturally changes to parameters won't be reflected.

What IE does sounds very strange to me and seems wrong.

Why not simply refer to parameters using '$test'?
