Deriving from other XS bound Perl-Module

[Tom Schindl]

Hi,

I'm fairly new to XS and have no idea how I could derive from another 
module which is bound to perl via XS.

e.g. I've XML::LibXSLT(XS-Binding to libxslt) and want derive from it 
XML::LibXSLT::Enhanced which adds new attributes.

Is this possible, using XS or even pure perl?

Tom
