It is. Although the means for doing so depends on which 
XSLT processor you're using.

For XT see: http://www.jclark.com/xml/xt.html#extension

For Xalan see: http://xml.apache.org/xalan/extensions.html

For SAXON see: http://users.iclway.co.uk/mhkay/saxon/extensibility.html

For a summary of the recent discussion (on XML-DEV and XSL-List) 
on why it would be a good idea to standardise this extension mechanism see:

"Unifying XSLT Extensions"
http://www.xml.com/pub/2000/03/29/deviant/index.html

Which is an article I wrote for XML.com last week.
