Uche,

XSLT 1.1 does not prevent this in any way.

The basic rules about a processor's built-in extension
functions do not change.

See the editor's note in Section 14.4 of the XSLT 1.1 working draft:

Ed. Note: Make sure that it is clear that it is allowed
          to call extension functions without using
          xsl:script to define them.

In other words, a processor can support "built-in" 
extension functions for any namespace with an "opaque"
implementation, just as an XSLT 1.0 processor can do
today.
