Troubles using Inodata Isogen Saxon Extension "renderedTextL

Hello Eliot!

I'm trying to use your Saxon extension (Function "renderedTextLength") with
Saxon 7.9.1 or Saxon 8.0 (hope this works because we don't use 6.5.3 any
more)
I copied the extension folder into the Saxon root folder.

In the stylesheet i defined the namespace as you did in your sample! I
started the formating in XML Spy (java -jar
"C:\Programme\Saxon\Saxon7.9\saxon7.jar" -o %2 %1 %3)

But then an error occurs which tells me that the function renderedTextLength
is unknown...

What is the problem here?

Thank you in advance!

Greetings
Markus
