I have tested the little used XSLT functions element-available() and
function-available() and made a stylesheet that can create a report
for most XSLT processors, testing also for EXSLT extensions and Saxon
extensions.

I have made 8 reports available and a summary, "Elements and functions
available in XSLT processors",
http://www.xmlplease.com/elements-functions.

Feel free to suggest improvements.
