I like this idea too – it could be a good solution to the problem that
filters are often very specific to the content they’re going to be
applied to.

As with Tab, I’m not sure about the feTemplate syntax, but I like the
idea in general.  I think we need to carefully think about what
parameters the filters are allowed to expose; we obviously don’t want
this to turn into a general templating solution.

There’s some overlap here with Doug’s SVG Parameters proposal, too, at
least conceptually:
