Assuming that we properly reference CSS Values & Units for the
definition of <length>/etc, then yes, calc() comes for free in places
that use <length>, as it's a type of <length>.  ^_^

The closest we have so far is the 'content' property, though it's
unclear how or if that applies to SVG content.  This is a topic
that'll be addressed when Doug Shepers and I flesh out the SVG
Parameters spec (which'll specify a way to "pass in" variables from a
referencing URL, so you can reuse a single SVG and alter the, for
example, colors dynamically), as we want the ability to specify text
in the same way you'll be able to specify colors/etc.
