Yes, I considered doing that, but for exactly the reasons you describe,
it's not guaranteed to do what you want.  And, conversely, I've seen
static files served with querystring parameters.

Agreed.  The default, global value of the audiomaxage property
will be non-zero.

That is, indeed, the case.  One major, popular VXML vendor did such
a bad job of cache management that I had to create different URL
paths for my entire project every time I changed anything, otherwise
it would always use the old cached value.
