RE: xsl processors turn off extension functions

Saxon provides this capability, but I don't know of any others.

You are right to highlight the importance of this feature. It's surprisingly
common to find sites that are prepared to execute untrusted stylesheets,
which can cause arbitrary havoc if extension functions are not disabled.
Even with extension functions disabled, there's a denial-of-service risk.
