Why did you pick Javascript?

The numbers for a Java (not Javascript) extension called from a Java
based XSLT processor are likely to be different.

I agree though that for the majority of stylesheets the difference
between using an extension and a ready written XSLT library such as
FXSL is not worth bothering about for performance reasons.  There
might be implications with regard to testing and validation though.
